Is your device installing apps itself without your permission? You wake up everyday with new unknown apps on your device?
If though you are for sure hit by the most spreading malware on android devices estimated to infect: 600,000+ Users Per Day.
The malware is categorized as a ghost push Trojan horse and it can't be uninstalled or deleted or force stop and even with factory reset it will remain !!
I will not only disable it as many sites offers but will actually remove it completely from the roots, it's an exclusive way of mine no one use it.
But before make sure your device is ROOTED as I need a rooted device for the operation, you can unroot the device back again if desired, please check this GiG: https://www.fiverr.com/shadyover/root-your-android-phone
