The Best Free Antivirus Software for 2026

What Is the Most Widely Used Antivirus Software?

Every Windows computer comes with Microsoft Defender Antivirus preinstalled, making it the most widely used antivirus software. However, if you’ve installed third-party protection, Defender stays on the sidelines. If no other antivirus is present or your existing antivirus expires, Defender steps up. Commercial antivirus apps offer protection beyond what’s included with Windows, but Defender is looking better lately, with some solid scores from independent testing labs. The combination of strong lab scores and a great score in our hands-on malware protection test raised its rating to 3.5 stars. As it is a free, built-in utility, we’re not including it in this roundup of commercial antivirus apps.

What Is the Best Free Antivirus Software?

You’ve come to the wrong place if you’re looking for free antivirus protection. Our list here covers the very best antivirus tools, and they’re not free. On the other hand, the best free antivirus appsbeat out many of their commercial counterparts. Consider Avast One Basic or AVG AntiVirus Free if your budget just doesn’t stretch to paying for antivirus protection.

What Is the Best Antivirus for macOS?

This roundup gathers the best antivirus tools for your Windows PCs. That doesn’t help if you’re strictly a Mac user, of course. We’ve created a separate collection of the best Mac antivirussoftware for you. You’ll notice some familiar names—our Editors’ Choice winners for Mac antivirus are Bitdefender Antivirus Plus for Mac and Norton AntiVirus Plus for Mac.

McAfee vs. Norton: Which Is Better?

Survey results vary for the most widely used commercial antivirus software, but Norton and McAfee generally appear at or near the top. Is Norton or McAfee better? Both rise above most competitors, but PCMag has identified Norton’s protection as outstanding, earning it an Editors’ Choice award.

What Is the Best Virus Protection According to Independent Tests?

We take the results reported by independent antivirus testing labs seriously. The simple fact that a company’s antivirus software shows up in the results is a vote of confidence. It means the lab considered the program significant, and the company felt the testing cost was worthwhile. Of course, high test scores are also important. We follow five labs that regularly publish detailed reports: AVLab Cybersecurity Foundation, SE Labs, AV-Test Institute, MRG-Effitas, and AV-Comparatives. We’ve devised a system to aggregate their results to yield a rating from 0 to 10. With perfect scores from all five labs, Norton currently tops the list. Also tested by five labs, Avast managed a 9.8-point aggregate lab score. ESET, with near-perfect scores from four labs, also managed a 9.8-point aggregate score.
