Hummer is a trojan that runs on Android operating systems.
This dangerous virus is installed by installing infected applications, usually through Google Play Store.
When a device is infected, Hummer will root the phone to gain administrator privileges, and then it will add pop-up ads to the phone. It then pushes mobile games and installs porn apps in the background. When a user attempts to uninstall them, they will be reinstalled.
This virus can be removed by antivirus apps that have this virus on their database, such as Clean Master.
