According to a test done by a German-based security institute AV-Test, nearly two-thirds of Android anti-virus are not yet suitable for use as reliable products.

The test found that out of 41 different Android anti-virus solution, 34 scanners detected less than 65 percent of 618 different types of Android-specific malware.

Software from companies including AVG, Bitdefender, ESET, Norton and Trend Micro detected between 65 and 90 percent of malware. In the second bracket of solutions, detecting only 40 to 65 percent of malware, fell products from BullGuard, Comodo, McAfee, NQ, Total Defense and G Data, leading AV-Test to conclude that “these vendors may not yet have a sufficient infrastructure to collect a broad range of malware or they focus on a local market.”
