how to choose antivirus

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, such as the ability to back up your contacts and other data, track your phone or tablet using its internal GPS chip, or even snap a picture of a phone thief with the device's camera.

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