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.
If your device doesn't have the virus and you still want to remove the pre-built chinese apps, You can use a program called MTK Droid Tools..
It was designed for mtk handsets but the Chinese software removal tool only uses adb and root access to remove chinese ime etc...
