Then, if you clarify your answer and give me more details I will be glad

Yeah that is not a virus itself, It is a application which you can use to control a another mobile by only accepting your BT connection... https://gallery.mobile9.com/f/3352386/
Do you have a java application supported mobile, Download the above application and turn the BT ON and search for mobiles.. if you connect the mobile with another mobile you can control the remote mobile. Thats all..
