If you do not know the name of the application you think has infected your Android phone or tablet, review the list and look for anything suspicious or you know that you have not installed or should not be running on your device.
In most cases, this is all you need to do to remove the virus, but you may occasionally find that the Uninstall button is dimmed .
This is because the virus may have taken control of the status of device administrator .
Exit the applications menu and tap configuration, security, device administrators . Here you will find a list of all the applications on your phone or tablet with administrator status. Simply uncheck the box of the application you want to delete then touch disable on the next screen
