Android.Circle in virus library:

Android.Circle is the family of Android malicious programs which combine both adware and clicker trojans functions. They are bots controlled by attackers via special commands. These trojans receive tasks in the form of BeanShell scripts and execute them using built-in open source BeanShell library.

Various modfications of Android.Circle trojans are created using Multiple APKs mechanism. It allows developers to upload several copies of a single application on Google Play to support different device models and CPU architectures. Thanks to this mechanism, part of the malicious functionality is implemented in separate APK files which are installed with the main application. As a result, discovery and analysis of such trojans is significantly complicated.
