Every once in a while, a fake antivirus pops up on the Google Play store. Most of the time, it’s just a fake scanner that doesn’t detect anything because it doesn’t actually look for anything to detect. Show a scan that simply lists all the apps on your device and it’s pretty easy to look legit. They serve up some ads for revenue, and you are given the false sense your phone isn’t infected—kind of a win-win unless you actually want malicious apps to be detected/removed.
These apps are often ignored by real AV scanners because, technically, they aren’t doing anything malicious. It’s only when malicious intent is found that these apps are classified as bad.
With a clean design and look, Antivirus Free 2016 could very easily be confused for a legitimate AV scanner.
