It didn't cause a slowdown on my test devices, plus it comes with an impressive list of features for a free program. I've chosen Sophos Intercept X (opens in new tab) as the best free antivirus app for Android because it does an excellent job of scanning for threats that have made it onto your device. Still, you will have to pay for these additional features after the trial period ends. You can try the Premium version for additional tools, including real-time detection and prevention of malware. It also recognizes phishing schemes, even in emails, and will alert you of them before you click through or provide personal information. Malwarebytes detects and stops ransomware before it can encrypt and hold hostage your files and programs. Another perk of Malwarebytes is, despite being a free antivirus program, it's completely ad-free. It doesn't use a lot of resources, so you won't experience slow down while Malwarebytes is running. This basic antivirus app won't stop malware infection but does an excellent job of rounding up malicious files, including adware, already on your devices. But if you don't need the extra features, then I highly recommend Bitdefender for all your devices. It doesn't have a VPN or anti-theft tools that some of the other apps include. The big reason Bitdefender Free Antivirus doesn't take the top spot is that it doesn't offer any other tools. Also, although Bitdefender is a free antivirus app, there aren't a lot of ads that get in the way. I didn't realize there was a scan going on until Bitdefender notified me that it was done. And Bitdefender dives deep into all your files on removable SD cards to ensure nothing is hiding anywhere.ĭuring my tests of Bitdefender Free Antivirus, I was able to keep working on my devices without worrying about my system running slower or lagging during a game. You don't have to use the autopilot feature, instead, starting and stopping scans manually. There isn't a safe browsing feature or phishing filters to stop attacks, but its autopilot scans your device often enough to catch threats before they become a problem. All this app does is scan your device for malware that may have made it onto your phone or tablet.
