Detecting and eliminating Chamois, a fraud botnet on Android

When it comes to Malware, the APKs spread all around the web are really dangerous as they are full of virus. Similarly, the Hack & coin generator kind of tools are also very dangerous for mobile malware. Such as this post hxtp://noxappplayer.com/dream-league-soccer-2017-hack/ might provide the hack tool but it is very difficult to say whether they are providing the right tool or not.

So beware of such websites and don’t get trapped by them just for getting something for free!
