10 Best Antivirus Software in 2025: Windows, Android, iOS, Mac
Short on time? Here’s the best antivirus for 2025:
- 🥇 Norton: Excellent virus and malware protection, with extras like anti-phishing, a VPN, a password manager, parental controls, live dark web monitoring, cloud backup, and much more.
There are hundreds of antiviruses out there — and they all claim to offer the best protection at the best price. But I tested the top antivirus software on the market, and only a few of them are strong enough, secure enough, and effective enough to be considered the best antiviruses of 2025.
Most antivirus programs include more than just a virus scanner — they also come with features that add additional protection, like a firewall, phishing protection, a virtual private network (VPN), a password manager, parental controls, and dedicated protections for mobile devices.
But a lot of antiviruses don’t work as advertised — they have poor malware detection rates, don’t consistently block malicious sites, and their extra features are badly designed and virtually useless (despite costing extra).
I spent weeks testing the top antiviruses on the market, ranking them on security, functionality, speed, and price. Norton came out on top, but I found 10 other products that are also excellent. They all come with money-back guarantees or free trials long enough to see if they meet your expectations. Read on to learn more about each of them and decide which is best for you.

300+ people found the right antivirus today
*This recommendation is based on our assessment; users are urged to consider individual factors before choosing a vendor.
Norton 360 offers unbeatable virus and malware protection. It’s a well-built and well-maintained internet security suite that keeps your devices and personal information safe — and it works well across all operating systems. It’s the best choice for home users looking for a complete, intuitive antivirus with some of the best cybersecurity protections out there.
Norton uses a unique scanning engine powered by heuristic analysis and machine learning, making it capable of scanning, finding, and removing all of the newest and most advanced types of malware. It scored a 100% protection rating during all of my tests and consistently scored higher on detection and threat prevention than built-in antiviruses (like Microsoft Defender).
- Secure firewall.
- Password manager.
- Phishing protection (including a private browser).
- VPN (with unlimited data).
- Dark web monitoring.
- Identity theft protections.
- Optimization tools.
- Parental controls.
- Wi-Fi security alerts (Android and iOS only).
- Cloud storage (up to 500 GB).
- Ransomware protection.
Norton’s phishing protections are excellent. They come as a browser extension that reliably blocks phishing sites, giving you detailed info on each site it stops you from visiting. It also has built-in online banking protection and a secure search engine that offers color-coded assessments of your search results. Finally, there’s a free browser called Private Browser that integrates various security and privacy-enhancing tools.
There’s also a free password manager. It generates, stores, and automatically fills in passwords, so you never have to remember them. Unfortunately, it lacks password sharing and a built-in TOTP authenticator that some standalone competitors include, but it does the basics well.
I really like Norton’s Android and iOS apps. Both versions have a spam filter, VPN, Wi-Fi security, web protections, and more. The Android app can even detect suspicious hardware and DNS spoofing attempts. The iOS version is less feature-rich, but this is true with all antiviruses.
The identity theft protections are really good, too. Norton’s LifeLock products (US only) offer various levels of protection and reimbursement, including up to $3M coverage in stolen funds, personal costs, and lawyer/expert expenses.
Norton’s VPN is one of my favorite antivirus-bundled VPNs in 2025. There are no data restrictions on any VPN plans, and all users get access to servers in 35+ countries. You’re also protected by 256-bit AES encryption and a no-logs policy. Other features include a kill switch, split-tunneling, and an ad blocker.
All in all, Norton offers more features than almost any competitor — and they all work great. It undergoes annual audits, complies with all major data privacy regulations, and has apps for all major operating systems (it even worked on my colleague’s Chromebook despite not being officially supported).
You can get basic protection for 1 device with the Antivirus Plus plan (INR2,640 / year), but I think the 360 Deluxe is the best-value package for most users. It costs INR4,390 / year and comes with the VPN, dark web monitoring, cloud storage, and more. For Norton’s full suite of identity theft protections, you’ll need a LifeLock subscription which starts at INR8,780 / year. All plans are backed by a 60-day money-back guarantee.
Bottom Line:
Norton 360 provides the best antivirus protection in 2025. It offers one of the strongest cybersecurity packages, complete protection from all malicious threats, and a ton of excellent extra features, like a VPN (with unlimited data), a password manager, secure cloud storage, parental controls, and a lot more. You can try Norton risk-free with a 60-day money-back guarantee.
🥈2. Bitdefender Total Security — Best for Lightweight Scanning + Tons of Additional Features
Bitdefender has an extremely advanced antivirus engine — it uses a massive malware database, machine learning, and artificial intelligence to detect and protect against malware more effectively than almost any competitor on the market.
In my tests, Bitdefender found and removed every malicious threat from my system. And because all malware scans take place on Bitdefender’s cloud server, there’s no strain on your device. In fact, when I put it to the test, Bitdefender averaged 21% CPU usage during full-system scans and less than 1% when running in the background.
But Bitdefender isn’t just a malware scanner — it’s one of the most comprehensive security suites available, providing some of the best protection for both computers and mobile devices, with features like:
- Web protection.
- Vulnerability scanner.
- System optimizer.
- VPN (200 MB/daily on most plans).
- Parental controls.
- Password manager.
- Webcam protection.
- Ransomware protection.
- Identity theft protections.
Bitdefender’s web protection is excellent — the built-in anti-phishing protection blocked the vast majority of phishing sites in my testing, and there’s a tracker blocker, too. I’m a big fan of Safepay, which is a secure, encrypted browser window for online banking and shopping. Some plans even come with Scam Copilot, an AI tool that alerts you to new scams, provides a chatbot that can identify scams, and more. I particularly love Bitdefender’s multi-layer ransomware protection, which adds a data-protection layer over your important files, so they can’t be encrypted during a ransomware attack.
Likewise, the vulnerability scanner looks for outstanding Windows updates, outdated applications, and weaknesses in your Wi-Fi network. When Bitdefender finds a vulnerability, it assigns it a risk level and offers advice on what you should do next. For example, I had an outdated version of Opera on my computer, and Bitdefender let me download the newest version or uninstall it.
Bitdefender’s VPN is also one of the best on the market, providing lightning-fast access to encrypted servers around the globe. Unfortunately, unlike Norton’s VPN, Bitdefender’s VPN limits your daily data usage on all but the most expensive plans.

Bottom Line:
Bitdefender offers cloud-based scanning and heaps of cybersecurity tools for a cheaper price than most competitors. I recommend Bitdefender if you’re looking for a comprehensive cloud-based cybersecurity suite with extras like a VPN, parental controls, and a password manager. You can try out Bitdefender risk-free with a 30-day money-back guarantee.
🥉3. TotalAV — Best for Ease of Use (Super Beginner-Friendly)
TotalAV has an excellent antivirus scanner and a couple of really good extras, all inside a very intuitive dashboard — making it a great choice for beginners. However, TotalAV also includes many customization options that advanced users will appreciate.
TotalAV’s antivirus scanner is fast and reliable, with near-perfect malware detection rates. The scanner caught 99% of all of my test malware, from viruses and trojans to ransomware, missing only a couple of tricky files (which Norton and Bitdefender managed to catch). Similar to Bitdefender, it didn’t have a huge impact on my system performance while running a scan.
TotalAV’s WebShield stops you from visiting dangerous websites. During my tests, it blocked the majority of dangerous websites I tried to visit. You also get access to Total Browser, a secure browser that blocks ads and dangerous sites. It even lets you know if a page you’re visiting was ever involved in a data breach.
Furthermore, TotalAV simplifies routine maintenance tasks by compacting them into 1 scan. This includes an antivirus scan, tracking cookie scan, and disk cleanup. I appreciate the amount of time this saves.
I particularly like TotalAV’s performance optimizer. Full virus scans will automatically check for junk to clean and settings to fix, but you can also scan exclusively for performance issues. It cleaned up more space on my computer than most other competitors.
I like TotalAV’s VPN, too. It’s secure, works with popular streaming sites, and maintains pretty fast speeds across all servers (which is why it ranks as one of the best antivirus-bundled VPNs on the market).
The password manager is pretty good. Total Password can safely store your passwords and other sensitive information in an encrypted space. You get all of the standard features, like auto-saving and auto-filling, a customizable password generator, cross-device synchronization, and more. It performed really well in my tests, with my only complaint being that it lacks password sharing. That said, it does include some pretty unique features like Secure Me — a tool that lets you remotely log out of accounts on all devices.
TotalAV is compatible with all major devices and operating systems, including Chromebooks. I like how it’s one the few antiviruses that works with Kindle Fire tablets. The only downside is that I couldn’t find information on internal security audits like I could with Norton or Bitdefender. However, it does regulate your data under the GDPR, so that’s one benefit.
My favorite plan is TotalAV Total Security, which covers up to 8 devices and costs INR4,310 / year. I like that it includes a VPN, premium password manager, and excellent ad blocker alongside all the other features mentioned above. If you’re on a budget, TotalAV Antivirus Pro is a good entry-level package for users looking to protect up to 5 devices, and it costs INR1,670 / year. All plans come with a 30-day money-back guarantee.

Bottom Line:
TotalAV has a powerful antivirus engine and a good range of features inside a user-friendly dashboard — I recommend TotalAV for first-time users just needing something safe, secure, and easy to use. TotalAV’s packages all have a wide range of features, and they’re all designed for maximum ease of use. Plus, all TotalAV purchases have a 30-day money-back guarantee.
4. McAfee Total Protection — Best for Online Security (+ Great for Families)
McAfee has a great range of internet security features, including malware protection, anti-phishing protection, a password manager, a VPN, and identity theft monitoring and coverage. All of its features are easy to use and work just as advertised. On top of mobile coverage, it even has an app for Chromebooks.
Its excellent virus protection makes McAfee a great choice — scoring a perfect 100% detection rate against all malware samples during my tests. McAfee detected, blocked, and removed both simple and advanced threats, including viruses, trojans, spyware, keyloggers, and rootkits.
Its anti-phishing protection is also excellent, preventing me from accessing known phishing sites and other dangerous web pages. It identified the vast majority of risky sites, outperforming built-in protections from browsers like Chrome, Firefox, and most competing antiviruses.
You can also protect your phone with McAfee’s mobile apps. Both the iOS and Android versions include the VPN, web protections, and a scanner that alerts you if you try to connect to unsafe Wi-Fi networks. There are unique features, too, like Scam Protection, which warns you about dangerous links in emails, texts, social media, and web browsers.
McAfee’s parental controls are also some of the best on the market — in addition to blocking inappropriate and unwanted content and apps, they come with advanced location tracking, which allows you to track your child’s device with almost perfect accuracy (this feature works much better than Google or Apple’s tools for locating devices).
However, McAfee slowed down my computer during full system scans (unlike Norton and Bitdefender). While I could browse the internet, use Microsoft Office, and watch videos on YouTube, I couldn’t play CPU-intensive games. That said, it may have a lesser impact on a different device, so I encourage you to try it out for yourself — all plans are backed by a 30-day money-back guarantee.
McAfee’s plans, which start at only INR3,520 / year, offer excellent value. The Essential plan (INR3,520 / year) provides coverage for up to 5 devices, and the Premium family package (INR6,150 / year) adds parental controls and coverage for an unlimited number of devices. There’s also the Advanced (INR7,910 / year) and Ultimate (INR17,560 / year) plans, which add identity theft coverage of up to $1 million and other protections.
Bottom Line:
McAfee Total Protection offers great internet security protection. Its anti-phishing and Wi-Fi protections are exceptionally good, blocking all risky sites and offering centralized security control from the McAfee mobile app, and its parental controls are some of the best on the market. McAfee packages include a commitment-free 30-day money-back guarantee.
5. Intego — Best for Comprehensive Mac Protection
Intego is the best macOS antivirus out there. Most antivirus brands only focus on protecting Windows PCs — but Macs need protection, too. All of Intego’s Mac antivirus packages provide high-quality internet security and optimization tools for macOS, greatly enhancing Apple’s built-in safety features with things like:
- Real-time malware protection.
- Mac optimization and cleaning tools.
- Advanced Mac backup options.
- Network security options.
- Parental controls.
Intego’s antivirus engine scored a perfect detection rate against all of my test malware (both macOS and PC malware). And its scans are fast — scanning over 800,000 files in under 2 hours. I really like that subsequent scans take only a few minutes, thanks to Intego’s file caching system that ignores already scanned files (Norton uses the same technology to skip over previously scanned files).
I’m also a huge fan of Intego’s customizable firewall — it monitors both incoming and outgoing network connections and alerts you to programs trying to connect to the internet. The firewall also adjusts its settings automatically depending on your environment — if you’re at home, work, or using a public Wi-Fi network.
Intego has cool additional features — I like how you can connect an external drive or an iOS device to your Mac and scan it with Intego’s virus scanner. This saves you from needing to get multiple antivirus packages to protect your iOS devices (if you want to do more than run antivirus scans on iOS, you’ll need to get a separate iOS antivirus app).
Intego’s Mac Premium Bundle X9 plan is excellent — it comes with all of Intego’s best features, including disk optimization tools and parental controls. There’s also the Mac Internet Security X9 plan, but it’s missing Intego’s excellent optimization tools. Starting at INR1,760 / year, Intego is a bit more expensive than the competitors, but then again, most competitors only offer basic programs for Mac users. All plans can cover up to 5 Macs and are backed by a 30-day money-back guarantee.
Intego also has a Windows product, Antivirus for Windows. It detected 100% of the malware samples I used to test it. You also get a VPN, optimization tools, and more. While it’s not as feature-rich as the best antiviruses for Windows, it’s still pretty good.
Bottom Line:
Intego is the best antivirus for macOS in 2025 (there’s a pretty solid Windows version, too). It offers excellent protection against Mac-based malware, greatly enhances and improves upon Apple’s already built-in security and device optimization tools, and comes with a 30-day no-risk money-back guarantee, so you’ll be able to see if it offers the best protection for you.
6. Panda Dome — Best for Flexible Pricing
Panda offers an advanced virus scanner, an easy-to-use interface, and flexible pricing. Its malware scanner performed well during testing. There weren’t many false positives, and though the scanner only detected 95% of malware, the real-time protections were still able to block every single threat I tried to add to my computer.
- Web protections.
- Optimization tools.
- VPN.
- Firewall.
- Parental controls.
- Password manager.
- Dark web monitoring.
- File encrypter.
- Rescue Kit (free bootable antivirus).
The extras aren’t as extensive or comprehensive as Norton’s. The optimization tools are effective — a quick one-minute scan cleared 1.2 GB of junk from my system, and the auto-updater is a handy feature.
However, some of the additional tools fall short. For example, the VPN has restrictive data limits and doesn’t allow server selection unless you opt for the most expensive plan. Similarly, the password manager’s auto-fill functionality works well but lacks many features typically found in standalone password managers.
I really like how Panda offers so many plans, letting you choose exactly the features and licenses you need. There’s even a decent free plan. Panda Free includes real-time virus protection for Windows, an app scanner for Android, a Rescue Kit, and a VPN (limited to 1 server and 150 MB per day). Just be ready for regular notifications telling you to upgrade if you choose this plan.
Essential, the most basic paid plan (INR2,200 / year) adds a firewall and Wi-Fi protection. The Advanced plan goes for INR2,510 / year and adds ransomware protection, while Complete (INR3,950 / year) gets you a password manager and various optimization tools. Panda Dome Premium adds an unlimited-data VPN and grants you 24/7 customer support for INR6,150 / year. All plans have a 30-day money-back guarantee and let you choose how many devices you want to protect.
Bottom Line:
Panda has flexible plans and many extras, including advanced ransomware protection, a Rescue Kit for saving malware-infected PCs, a password manager, parental controls, and a file encrypter and shredder. All of Panda’s premium plans are backed by a 30-day money-back guarantee.
7. Kaspersky Premium — Best for Online Shopping + Banking
US users can’t currently buy a Kaspersky antivirus subscription following the Biden administration’s ban on the company’s products. This has also led Google to remove Kaspersky’s app from the Play Store, but you can still download it on Android via Kaspersky’s official site. Regardless, we currently have no evidence to suggest that Moscow-based Kaspersky is a threat to users. Kaspersky is GDPR compliant and has passed an independent SOC 2 audit, something not many competitors can claim. You can read more about our decision to continue recommending it on our website here.
Kaspersky has excellent antivirus protection, plus some impressive bonus features like dangerous site protection that keep you safe online. Its antivirus engine consistently delivers some of the best results — the program was 100% effective at keeping my devices safe.
- Anti-phishing protection.
- Parental controls.
- Webcam protections.
- Safe Money secure browser.
- VPN (unlimited data).
- Password manager.
- Smart Home Monitor.
I really like Kaspersky’s Safe Money feature — the program detects when you’re about to make a payment online or access a banking website, offering to launch a safe, sandboxed browser window that’s impenetrable to malware and spyware. Though, I slightly prefer Bitdefender’s secure browser, Safepay, which loads much faster than Kaspersky’s. Kaspersky also lets you use a virtual keyboard when handling online payments to avoid keyloggers.
The vulnerability scanner is good, too. It quickly scanned my computer and alerted me to any vulnerabilities it found — including one in Firefox that I didn’t know about.
The Smart Home Monitor is a nice addition. With just a few clicks, you can view a list of all devices connected to your network. If you see anything that shouldn’t be there, you can take steps to ensure your network is secure, like changing your passwords.
Kaspersky has 1 free and 3 paid plans. The free plan gives you basic protection on a single Windows device. To protect your Android, MacOS, and iOS devices, you’ll need to upgrade to a paid plan. While Kaspersky Standard and Plus are both good options, Kaspersky Premium is the best-value plan, providing malware scanning, web protection, the Safe Money secure browser, an unlimited-data VPN, a password manager with unlimited password storage, home Wi-Fi monitoring, plus 1 free year of Kaspersky parental controls for up to 1 user. At only INR3,050 / year, this is a good deal — and there are also options to cover 5, 10, and even 20 users depending on your location and the plan you choose.
Bottom Line:
Kaspersky offers a well-designed antivirus package with a good anti-malware scanner. In addition, you get useful extras like a secure browser, a VPN, a password manager, and 1 free year of parental controls. All of Kaspersky’s plans have a 30-day money-back guarantee.
8. Avira Prime — Best for System Optimization
Avira has one of the most robust antivirus engines around — it consistently scored a 100% detection rate during all of my tests, and it’s so good that Avira’s anti-malware technology has been licensed out to several competitors, including TotalAV. It works on most operating systems, including ChromeOS.
Avira Prime also comes with a lot of really good additional features, such as:
- Privacy optimization.
- System optimization.
- VPN.
- Password manager.
Avira’s system optimization tools are some of the best on the market. While many antiviruses include tune-up tools designed to help your device run smoothly and free up hard drive space, Avira comes with one of the most advanced tune-up and clean-up tools bundled with an antivirus, including:
- Startup optimizer. Saved a full 2 minutes from my PC’s start time!
- Game booster. Automatically allocates system resources and stops background processes to improve system performance
- Junk file cleaner. Removes duplicates, unused files, and some cached files.
Avira Prime is a particularly good antivirus if you have an old or slow PC that’s often low on hard disk space. Its 1-click optimization tool was able to remove far more junk than many competitors, and the Game Booster actually had a noticeable effect in my tests. There’s also a duplicate file finder, a streamlined driver updater, and more. And since Avira’s antivirus engine operates entirely in the cloud, it won’t slow down your devices like many other competitors do.
At INR5,270 / year, Avira Prime is a good value, but it’s pricier than some top-rated antivirus packages. Avira does have cheaper plans, including Internet Security (INR3,080 / year), but Prime is the only package that includes advanced system optimization, an unlimited-data VPN, and premium mobile apps.
Avira’s free version is one of the better free antiviruses on the market — if you don’t want to spend any money right now, Avira Free can protect your device with real-time protection, ransomware protection, and even a free version of Avira’s VPN.
Bottom Line:
Avira protects users with a lightweight cloud-based scanner and also offers excellent system optimization tools. It also has a VPN, password manager, and coverage for up to 5 devices across all operating systems. You can try out Avira risk-free with a 60-day money-back guarantee.
9. Trend Micro — Best for Secure Web Browsing
Trend Micro has a decent anti-malware engine, good diagnostics tools, and an excellent web browser extension that blocks online scams and unsafe websites. The antivirus scanner scored pretty well in my testing, catching the majority of viruses, trojans, ransomware, and spyware on my system, though it didn’t score as well as top competitors like Norton. Trend Micro also offers several scan customization settings, allowing users to adjust the malware protections.
Trend Micro detected more phishing websites than Chrome, Firefox, or Safari when I tested it. In addition, it detected scam links, unsafe content, malicious code, and even misinformation, and it also blocked ads and scanned my browsing history for any dangerous sites I may have visited.
Trend Micro also includes a password manager, secured with 256-bit AES encryption. It offers basic features like unlimited password storage, password generation, basic auto-fill, and 2FA. Though it has an ad blocker, it still isn’t as intuitive or feature-rich as standalone options like 1Password and Dashlane.
Starting at INR1,760 / year, Trend Micro offers several plans to choose from, but my favorite plan is Trend Micro Maximum Security, which protects up to 5 devices and adds a password manager for INR4,390 / year. The most comprehensive plan, Premium Security Suite, costs INR4,830 / year, covers up to 10 devices, and adds various identity theft protections and a fully-featured VPN.
Bottom Line:
Trend Micro offers a strong set of malware and internet security features for Windows, Mac, Android, iOS, and Chromebook users. It’s particularly good at web protection, and its browser extension will help you avoid malicious websites, scam links, and suspicious content. All Trend Micro plans are backed by a 30-day money-back guarantee.
10. Malwarebytes — Best for Basic Protection
Malwarebytes is a simplistic, easy-to-use antivirus that offers good virus protection for all operating systems and devices, including Chromebooks. During my tests, Malwarebytes’s advanced malware scanner detected around 95% of my test malware, which is pretty good (but not as good as top competitors like Norton).
Malwarebytes also offers a VPN with unlimited data, servers in 40+ countries, and decent speeds. However, Malwarebytes’s VPN isn’t a good choice for streaming or torrenting (if you’re looking for a good VPN for streaming and torrenting, I recommend ExpressVPN).
That said, I’m a big fan of Malwarebytes’s web protection, which successfully identified and blocked most of the phishing sites I tried visiting during testing, as well as ads, trackers, and other potential scams. The ad blocker struggled with video ads, but I like that the extension provides a record of everything it blocks.
I really like Malwarebytes’ exploit protections. It’s fairly customizable and helps Malwarebytes to be effective against zero-day exploits as well as malware. Malwarebytes has some good identity theft protections in their Identity plans, too. There’s social media monitoring, credit monitoring for US customers, and more.
Unfortunately, Malwarebytes is lacking when it comes to additional features. It doesn’t have a firewall, and the parental controls and optimization tools are limited. Nevertheless, it’s a good choice for users looking for a decent antivirus program they can install and forget about. Malwarebytes starts at INR3,950 / year.
Bottom Line:
Malwarebytes is a minimalistic antivirus program, offering effective malware scanning and web protection. It provides a reliable VPN, a user-friendly interface, and identity theft protections (as an add-on). Malwarebytes is a solid choice for those seeking basic protection, and it comes with a 60-day money-back guarantee.
Bonus. MacKeeper — Intuitive & Feature-Rich Antivirus for Mac
MacKeeper is one of the rare antiviruses specifically designed for Mac. It comes with good malware protection, a range of security and privacy features that build upon Apple’s native protections, and a very intuitive macOS app.
I tested Mackeeper using my Macbook Pro (M2 Chip), and it detected 98% of Mac-specific malware files, similar to the best antiviruses for Mac, including Intego and TotalAV. Its Mac cleanup and optimization tools removed around 7 GB of junk and duplicate files from my MacBook Pro (I also really like how MacKeeper offers the option to delete unwanted email attachments, which is something I haven’t seen in any other antivirus).
MacKeeper’s VPN is also really good — secure, fast, and compatible with most streaming sites. The only thing I dislike about the VPN is the lack of transparency regarding the no-logs policy. I’d like to see MacKeeper provide clearer information on how it manages user data.
On the other hand, MacKeeper is missing anti-phishing protection, a crucial security feature for an antivirus in 2025. It also doesn’t have a firewall or parental controls, which are included with Intego.
MacKeeper offers several plans that start at INR5,020 / year. The plans are all the same; the only difference between them is in the subscription length and the number of Mac computers covered (1–3).
Bottom Line:
MacKeeper is a good Mac-only antivirus — it has near-perfect malware detection rates, includes excellent system cleanup tools, and offers a secure and fast VPN with unlimited data. However, it’s missing anti-phishing protection, a firewall, and parental controls. MacKeeper offers several paid plans and backs annual subscriptions with a 30-day money-back guarantee.
Testing Methodology: Comparison & Ranking Criteria
When rating products, I followed our tried and tested methodology. I ran real-life scenarios with criteria that included checking security, speed, ease of use, value, and customer support. In particular:
- I tested malware detection rates and scanning capabilities. I conducted dozens of malware tests, real-time protection tests, CPU performance tests, and more. Once done, only the products that protected against the most advanced malware threats made it to this list. Norton did the best here, but the other antiviruses on this list performed well, too.
- I looked for high-quality add-ons. Most antiviruses offer additional features in their paid antivirus packages, but some are basically useless. I tested each feature included with the products on this list to guarantee that they’re genuinely useful and effective. Bitdefender has a great range of helpful features, but many others do, too.
- I tested for speed and efficiency. The best antiviruses are lightweight and run smoothly — even on older or slower computers. I tested and measured how quickly and efficiently each antivirus on this list performed and awarded extra points to those that didn’t cause any slowdown.
- I checked for multi-platform support. The top antiviruses are compatible with most operating systems, including less popular ones like ChromeOS or FireOS. While not all of my top choices support all platforms, most antiviruses I tested worked flawlessly across multiple operating systems.
- I evaluated the value of each product. Antivirus software can be a big investment. I considered all relevant factors, such as web and browsing protection and how many devices are covered. All of these top antiviruses provide great value.
How to Choose the Best Antivirus for Your Operating System
Choosing the best antivirus for your operating system requires a bit of planning. To ensure you get the one that suits you, you should:
- Step 1. Identify your operating system’s specific needs. All types of operating systems need antiviruses to stay safe from threats, but not every antivirus works on all devices. Find an antivirus that supports the platform you use. Beyond that, it’s worth considering products with a strong track record of protecting your particular device (Norton works great on Windows, while Intego is geared toward Mac users).
- Step 2. Check that the antivirus has all the features you want. Top antivirus software comes with various features beyond basic virus detection, but each antivirus offers a somewhat different toolset. Consider what you use your computer for the most to decide what features are for you.
- Step 3. Compare the price with other antiviruses on the market. Antivirus pricing can vary widely depending not just on features but also on subscription length. Comparing prices helps ensure you get the best deal without overpaying for features you might not need.
Here are our curated lists of the best antiviruses for different operating systems and devices below:
- Best antiviruses for Windows. The market is huge, but after extensive research, testing, and comparison, I recommend Norton as the top pick for Windows.
- Best antiviruses for Mac. Unfortunately, because most antiviruses focus on Windows, many provide only bare-bones versions of their Windows software for Mac users. However, several macOS antiviruses provide good malware protection, improve upon Apple’s built-in protections, and are easy to use on Mac devices. Our top choice for macOS is Intego.
- Best antiviruses for Android. While there’s no shortage of Android antiviruses, most aren’t good enough to fully protect your device. We identified a handful of apps that provide excellent malware and web protection, as well as extras that can further secure your online activities. We recommend Norton or Bitdefender as the top Android antiviruses.
- Best antiviruses for iOS. While it’s true that iOS devices can’t get viruses, they are vulnerable to a wide range of other online threats, including phishing scams, spyware, adware, and identity theft. The best iOS antiviruses can keep your device and data safe from these threats. Our #1 antivirus for iOS is Norton.
- Best antiviruses for ChromeOS. Chromebooks have unique security features but are still vulnerable to online threats. I recommend Chromebook users get an antivirus, but you need to choose carefully as most antivirus don’t work well on ChromeOS.
Quick Guide: How to Use an Antivirus
1.Install from a reputable source. Navigate to the website of your chosen antivirus. is my top pick, so I’ll use it as an example here.
2.Choose a plan that suits your needs. Review all of the plans your antivirus provider offers to find the best one for you. Don’t forget to look for a money-back guarantee (Norton, for example, offers a 60-day money-back guarantee on all of its plans).
3.Set up your account. Once you’ve chosen and purchased a subscription, it’s time to register with the antivirus provider. Provide your details and click Create Account.
4.Perform an initial full system scan. Download and install your antivirus software, then run a full system scan to check for any existing threats on your device. This may take some time, but it’s crucial.
5.Schedule regular scans. Besides real-time protection (turned on by default in Norton), schedule regular full system scans to search for any malware that might have slipped through.
6.Use additional security features. Explore and utilize additional features, such as a firewall, web protection, anti-phishing, and parental controls. Norton, for example, has an excellent free browser extension, Norton Safe Search, which you can install to enhance your online security.
7.Stay informed about new features. Periodically review your antivirus software’s documentation or news updates to learn about new features or settings that can improve protection. Norton’s official website, for example, features a dedicated product & service announcement blog, where you can read all about the latest updates to its antivirus program.
Following these steps will help you maximize the effectiveness of your antivirus software, keeping your digital environment secure against a wide range of cyber threats.
Built-In vs. Third-Party Antiviruses — Which Is Better?
A reliable third-party antivirus is always a better option. The built-in protections of Mac and Windows operating systems cannot match the comprehensive security offered by a premium antivirus. While the basic free protections these systems provide are a good start, they don’t offer sufficient defense against advanced threats in 2025.
On Windows
If you’re a Windows user, you’ll have Windows Security on your computer (formerly known as Windows Defender). While it’s a decent free antivirus, it scores consistently lower for malware detection than top standalone brands like Norton and Bitdefender. It also lacks performance optimization tools, a password manager, a dark web monitor, and more.
Windows Defender will usually turn itself off when you install a third-party antivirus. It can do so modularly, so the default firewall will stay on if it detects that your antivirus doesn’t have one. Some premium products like Malwarebytes are even designed to be used in tandem with Windows Defender.
On macOS
Macs have a few built-in security features, including web protection, anti-theft tools, app review tools, and an app scanner. These are useful, but on their own, they’re not enough to keep you safe. Your Mac could still be vulnerable to advanced ransomware, spyware, adware, and other threats.
For enhanced protection on Mac, consider using a premium Mac-specific antivirus such as Intego. It provides impeccable malware detection, effective Mac cleanup tools, parental controls, and numerous other features. In addition to installing Intego or another macOS antivirus, you should follow our tips for keeping your Mac secure.
What Security Threats Can an Antivirus Protect You Against?
A quality antivirus provides strong protection against most security threats. Here are the most common ones:
- Viruses. A type of malware that can self-replicate and make unauthorized changes to your computer.
- Potentially Unwanted Programs (PUPs). PUPs are software that can modify your browser settings and fill your screen with ads. Browser hijackers and other PUPS aren’t necessarily malicious or illegal, but they tend to be annoying and invasive.
- Adware. If you’re seeing an uptick in ads, adware could be the cause. Adware is a type of malware that drowns you in advertisements. They can interfere with your device even when you’re not connected to the internet, causing frustration and collecting data.
- Spyware. In the best scenario, a spyware infection could lead to eerily targeted ads. But often, the situation is much worse, with keyloggers stealing passwords and total surveillance tools like Pegasus watching your every move.
- Trojans. Arguably the most dangerous type of malware, trojans are viruses that initially appear to be normal programs. But after certain conditions are met, they act maliciously, replicating themselves across your network, stealing data, and damaging devices.
- Worms. Worms are viruses that automatically spread, infecting everything they can. Unlike trojans, they cause damage immediately. This could involve corrupting files, operating systems, or spamming annoying messages.
- Ransomware. A type of malware that encrypts files to hold for ransom — ransomware will display a message with instructions about what you need to do to regain control of your device. Tools like Cl0p and ransomware gangs like Akira target tens of millions of users each year. The best defense is an antivirus with ransomware remediation (such as Bitdefender) that will halt the encryption process, as there’s no guarantee that cybercriminals will relinquish control even if they’ve been paid.
- Rootkits. Rootkits are a particularly dangerous type of malware that can seize administrator privileges and otherwise make critical changes to computers.
- Browser exploits. A good antivirus (like the ones on this list) will automatically detect suspicious activity in your browser, preventing hackers from using vulnerabilities to change your browser’s settings or perform other malicious actions. This includes threats that leverage JavaScript injections like SocGholish.
- Phishing attempts. Phishing is a method that criminals use to steal personal information and take over accounts. Antiviruses are built to detect web-based phishing attempts, usually through databases of malicious websites.
In essence, antiviruses guard against all key online threats, and the top ones are incredibly successful in fulfilling this role. However, it’s crucial to remember that nothing is flawless – even when equipped with the best antivirus, you must still exercise caution online.
Why We Still Recommend Kaspersky
In essence, antiviruses guard against all key online threats, and the top ones are incredibly successful in fulfilling this role. However, it’s crucial to remember that nKaspersky has found itself at the center of controversy due to its ties to Russia. The tensions culminated when, in July 2024, the Biden administration banned the sale of Kaspersky Lab’s antivirus software in the United States. The ban prohibits new sales, software updates, and licensing of Kaspersky products after 29 September 2024.
These developments have left many of our readers wondering about the safety and reliability of Kaspersky’s products, prompting a closer examination of the company’s history, product offerings, and the potential risks associated with using its software.
We maintain that, at this point, there is no evidence to suggest Kaspersky is unsafe. In 2017, Kaspersky started its Global Transparency Initiative — it moved its data storage centers to Switzerland, opened Transparency Centers in Switzerland, Spain, Canada, Brazil, and Malaysia where its source code and software updates are continually assessed, and passed the Service Organization Control for Service Organizations (SOC 2) Type 1 audit.
What’s more, Kaspersky has exposed many cases of cyber espionage, including those perpetrated by both Russia and the US, and its researchers are among the most well-respected in the industry.
Given all this, we have no reason to think Kaspersky is a threat to users. But if you’re worried about Kaspersky putting your online security at risk or are shopping for a replacement, there are a few great alternatives to choose from, including Norton or Bitdefender.othing is flawless – even when equipped with the best antivirus, you must still exercise caution online.
