    You can try doing a hard reset?

    1.Power off your phone
    2.Press power button and after phone vibrates once press volume down until you will see exclamation sign on the screen
    3.Press in the following order: volume up - volume down - power - volume down
    4.Wait until format ends and the phone restarts

    Just follow the suggestion posted by grossmuttr to perform "HARD RESET".

    After restoration, becare when downloading app's (video's files,games..ecc) next time because such problem(s) are strong indicated that our device as been infected.


    Thanks (I hope it help)
