How to remove gunpowder virus? I have recently been having problems on my device which includes random apps appearing on my phone and some chinese app that somehow was "pre-installed". As i scoured the internet for answers, i  learnt that my phone had contacted a virus called gunpowder virus that attacks from Nintendo emulators. Can factory reset resolve my problem?
As long as the infected app wasn't able to gain root and/or infect the /system partition, a factory reset will fix it.

However, if it was ... it would require re-flashing the ROM.
