AV-TEST Institute evaluates various Android virus scanners
The AV-TEST Institute, an independent anti-virus research provider, inspected 41 different virus and malware scanners for Android specifically testing for detection performance.
According to the report, about half of the scanners are not yet suitable for use mainly due to reliability of detection, with some products scoring a detection rate of less than 65% out of the 680 types of malware tested.
The final list of solutions were rated either "good" (detection rate of 90% or higher) or "very good" (a detection rate of between 65% and 90%). The Institute acknowledges though, that products which scored between the 65% and 90% mark could move on to the top range depending on changes to the malware test set as some of these products only missed one or two malware families which may not even be prevalent in certain environments.
