Best Android Antivirus Apps

If you're not running some kind of anti-malware app on your Android smartphone or tablet, then you're putting yourself at risk of infection from corrupted apps and other kinds of malware.

The good news is that your options are far from limited. The best mobile antivirus apps offer not only top-notch malware detection and prevention, but also a range of privacy and anti-theft features. These include the ability to back up your contacts and other data, track your phone or tablet using its internal GPS chip, snap a picture of a phone thief with the device's camera, and even use your Android Wear smartwatch to locate your phone.

Most mobile security apps have both free and paid versions, but not all freemium antivirus products are created equal. We've rounded up apps from the biggest names in mobile antivirus protection — Avast, AVG, Bitdefender, Kaspersky, Lookout, McAfee and Norton — and rated their apps based on setup, interface, usability, extra features and, of course, their anti-malware chops.

To gauge security protection, we used data from AV-Test, which rates most major security apps based on their ability to detect zero-day malware and other recent threats. We also used the Geekbench 3 app to measure the impact these security apps have on overall performance.

  • bought the bitdefender one for 25ish pounds.

    Got a non working activation key in return. And i had to delete my free 1 years trail of Kaspersky which worked just fine!
  • Comodo Internet Security seems to work well with little system slowdown compared to most products. Offers FREE antivirus and firewall which beat the Microsoft and most paid programs. Has caught virii & blocked malware that other products would have allowed. I do supplement the anti-malware scans for peace of mind sake, but then I haven't found products with the others that weren't already identified by Comodo.
  • Here is a critical test that I think should be included in every antivirus program test: Impact on TimeMachine. I had Avira installed on my computer - and as a result, a backup of 20GB of data with TimeMachine would take more than three days. I had to uninstall Avira - and now my backup is back to normal.
  • What is "normal"?
  • I think you may want to check out ESET AV.
  • Originally Avira Free didn't bug you to upgrade as I have used it for years. Now it does.
