The best antivirus software for Windows 10 is Bitdefender, McAfee, and Norton. These programs protect you against viruses and malware, but they have different features and functionalities. Bitdefender provides affordable and proven protection, Norton's higher-tier plans add extras like cloud storage, a VPN, and parental controls, and McAfee can cover all of your devices with one subscription.

Choosing the right antivirus usually comes down to how you’ll use it. Below, we give you what we liked, what features were lacking, and who would benefit most from each of our favorites.

If you're running Windows 10, note that Microsoft has extended free security updates to October 2027 — but those patches won't last forever. A trusted antivirus helps fill the gap when official support finally ends.

How we test and rate antivirus software

Our team has conducted hands-on testing on 30+ antivirus programs. Each product is tested by a dedicated reviewer on a rotating basis across Windows, macOS, and Android using a subscription purchased with our own money.

We evaluate each product across seven areas:

  • Test results (49%): We measure quick scan speed on a standardized test device, run our own in-house EICAR tests for malware detection, drive-by malware, and phishing protection, and average each product's most recent AV-TEST scores across Windows, macOS, and Android.
  • Editor's score (20%): We evaluate the product's ease of use, onboarding experience, and overall trustworthiness.
  • Core features (20%): We determine if the product includes real-time protection, manual and scheduled scans, ransomware protection, a firewall, network protection, webcam and microphone protection, and phishing protection.
  • Value (3%): We compare the lowest plan price, money-back guarantee length, and maximum device coverage against competitors at the same price point.
  • Compatibility (3%): We assess availability across desktop and mobile platforms.
  • Customer service (3%): We determine the quality of the methods available for direct support, including live chat, phone, and email.
  • Bonus features (2%): We check whether the product includes additional tools like tune-up services, a password manager, an ad blocker, identity monitoring, parental controls, and a VPN.

We retest all antivirus products at least once a year and update our reviews to reflect any changes. To learn more about how we test, read our full antivirus testing methodology here.

What we liked

Bitdefender is best for anyone who wants top-tier protection without paying a premium for it, plus a few extras like a file shredder and a VPN.

Bitdefender's dashboard
Bitdefender's user-friendly dashboard

Strong test results: Bitdefender passed our EICAR testing and received great scores from the independent third-party tester AV-TEST. If you want strong, well-tested protection at a lower price than most competitors, Bitdefender may be for you.

Tons of extra features available: While the basic plan offers some features to go with its solid protection, you can always upgrade for more extras and additional devices covered. The all-in-one plans offer an unlimited VPN, password manager, and other features that cost a little more but are still reasonably priced.

What we didn’t like

We didn’t like the reduced features on Mac products. While this shouldn’t matter to Windows users, some people have more than one operating system on various devices. 

We also wish Bitdefender’s third-party testing scores had remained perfect. During this round of testing, the software suffered from a slight dip in performance and usability. That doesn’t mean it didn’t provide exceptional protection, but it was just a hair slower than before and had a few more false positives.

Test results

To get an accurate view of Bitdefender's malware detection abilities, we reviewed results from independent testing organizations, including AV-TEST, AV-Comparatives, and SE Labs.

Bitdefender earns perfect or high scores with AV-TEST, AV-Comparatives, and SE Labs. It also routinely passes our in-house EICAR tests.

AV-TEST Windows score 18/18
AV-TEST macOS score 18/18
AV-TEST Android score 18/18

Bitdefender's 5.0 star rating is backed by consistently excellent real-world performance across our own testing and every major third-party lab. It blocked every malware, phishing, and drive-by threat we threw at it, ran scans without slowing down the device,

Bitdefender also has a feature list that goes well beyond basic protection: ransomware defense, firewall, webcam and mic protection, parental controls, VPN, and a password manager. There's even a free plan for Windows users.

  • Passed every malware, drive-by download, and phishing detection test we ran, quarantining threats automatically
  • Backed by a 100% Virus Protection Promise: if Norton can't remove a virus, you get your money back

What we liked

Norton is best for anyone who wants a lot of additional features, as long as you pick the right tier. The entry-level plan covers antivirus, scam protection, cloud backup, and a password manager. 

With Norton 360 Standard or Deluxe and you'll add a VPN, dark web monitoring, and parental controls. It's a strong security stack once you land on the tier that has what you need.

Full suite of Norton security tools

All-in-one software: Norton's higher tiers let you cover a lot of ground with one purchase, from device protection to parental controls. Just check the tier comparison before you buy, since the extras aren't all bundled into the cheapest option.

Lots of security: We’re also impressed by Norton’s comprehensive security coverage, which includes protection against viruses, malware, phishing, and even hacking. Norton has been in the security industry for a long time and uses its knowledge to its advantage.

What we didn’t like

We don’t like Norton’s renewal pricing. No matter what plan you get, it’s guaranteed to go up upon renewal. Norton is one of the pricier antivirus companies, so there’s always a little bit of sticker shock when we see the plans.

We’re also not thrilled with how much navigation you have to do. All the extra features are great, but the dashboard includes a host of tabs that may feel overwhelming to some users. We love a good user experience, but Norton may offer too much.

Test results

To see if Norton 360 is really as good as it claims, we also looked at test results from other independent testers. This gave us a better idea of how well Norton detects malware.

Norton received perfect scores across almost all of the third-party tests and with our in-house tests as well. It only received a less-than-perfect score in the AV-Comparatives malware protection test.

What we liked

McAfee is best for anyone who has a lot of devices to cover. If you have a large family or a lot of computers, McAfee has a tier that includes unlimited devices so you can keep everything protected.

McAfee in the process of a Smart Scan

Can cover unlimited devices: We like that McAfee offers users the ability to cover an unlimited number of devices, which isn’t something we normally see in security products.

Tons of options: Additionally, we liked the amount of options offered for McAfee products. The company understands that different people have different needs and tries to offer products that fit everyone. You have a higher chance of finding a plan that works for you with all the options available — we love having options.

What we didn’t like

We didn’t like that the included VPN has a data cap. In fact, the included VPN wouldn’t work as a sole VPN for anyone who values privacy or loves streaming. We love a good bundled product, but each piece has to hold its own. We don’t think McAfee’s VPN does.

We also found that McAfee sends a few too many text notifications. If you enable that feature, you might disable it pretty quickly. It was almost spammy — not our favorite.

Test results

When we tested McAfee, we also looked at test results from other independent antivirus testers. This gives us a better idea of how the antivirus copes with malware detection and prevention. We looked at test scores from AV-TEST, AV-Comparatives, and SE Labs.

McAfee received perfect scores in both third-party and in-house testing.

AV-TEST Windows score 18/18

Star rating summary

During our testing, it was no surprise that McAfee earned nearly perfect scores across the board. The only thing that held it back was its long scan times, which made it a less convenient choice over other available options. 

McAfee still did its job well, so that wait may be worth it for you.

What's the best free antivirus for Windows 10?

If you’re looking for protection without a lot of frills, some free antivirus providers can offer solid security. We usually discourage free software because it’s often untrustworthy, but we’ve tested the solutions we’ve included below and found them reliable.

Windows Defender Antivirus

4.9
Antivirus Software
Microsoft Defender
  • Brings the well-loved Microsoft antivirus to other devices
  • Includes dark web monitoring, identity theft insurance, and restoration services
  • Bundled with premium Microsoft 365 productivity apps and cloud storage
  • Confusing paid extras on top of the free built-in antivirus for Windows
  • Slow scan speeds
Learn More

Windows Defender comes built into every Windows 10 and 11 device, so there's nothing to download or install. It runs real-time protection in the background, scans files as you open them, and includes basic firewall and network protection. 

Microsoft has committed to keeping Defender's malware definitions updated on Windows 10 through at least October 2028, so it keeps catching new threats even as the OS itself ages out of standard support.[1]

What happens when Windows 10 loses support?

Microsoft ended mainstream support for Windows 10 on October 14, 2025. That means no more feature updates, no technical support, and no automatic security patches for most Windows 10 devices unless you're enrolled in Extended Security Updates (ESU).[2]

Microsoft has since extended the ESU program for consumers, so you can get critical security patches through October 12, 2027. Enrollment is free if you back up your settings with a Microsoft account through Windows Backup. You can also enroll by redeeming 1,000 Microsoft Rewards points or paying a one-time $30.00 fee.

ESU only covers security patches, though. It won't fix bugs, improve features, or give you technical support. 

If your PC can't run Windows 11, or you're just not ready to switch, a strong antivirus becomes more important. ESU protects the operating system itself, but it doesn't protect you from phishing, ransomware, or malware that a good antivirus would otherwise catch.

Bottom line: The best antivirus programs for Windows 10

Bitdefender, Norton, and McAfee are your strongest picks for Windows 10, and which one wins depends on what you're optimizing for.

If you want the strongest all-around performer, Bitdefender is our top pick, with excellent malware protection and useful extras like a file shredder, all starting at $34.99/first yr. For one subscription that covers everything, Norton's higher-tier 360 plans bundle a VPN, parental controls, and dark web monitoring alongside antivirus, so you're not stitching together separate tools. And if you've got a house full of devices to protect, McAfee's unlimited-device tier means you stop counting licenses.

One thing that applies no matter which you pick: if you're still on Windows 10, staying safe online matters more now than it did before October 2025, since the OS itself gets less support than it used to. A strong antivirus won't patch Windows, but it's your best defense against the threats that slip through that gap.

FAQs

Is Windows Defender any good?

The antivirus software built-in for free in Windows 10 and 11 devices is now known as Microsoft Defender Antivirus and it's pretty good overall, especially for protecting your device against malicious files you accidentally downloaded. 

However, it doesn't provide additional protection, such as phishing detection, network scanning, VPN protection, and more, which most premium third-party software includes.

Will antivirus software slow down my computer?

There’s always a chance that antivirus will slow your computer down. If you choose a product with a small footprint, it’s going to be much easier on your processing systems than one that downloads all its contents onto your device.

You should, however, always use some kind of antivirus software to protect yourself online.

Is Norton owned by Microsoft?

No, Norton is not owned by Microsoft. Symantec, the company that’s owned Norton since 1990, is a leader in global security. In 2014, Symantec split into two companies, but it continues to own the Norton brand.
