After factory reset, malware is still there.

[MarshallLeeTheVampireKing]

I accidentally installed a malware. It was from an app that rewards you with gift cards. I know it was stupid. The app I installed was like a clean master but with a red logo and it's full of incorrect grammar. Last night ads started popping up. I noticed apps without icon on the app drawer. I uninstalled everything that I installed that day. I also deleted the apks that is in my sd card even though I did not download it. The apps kept installing themselves, so I had no choice but to factory reset it in recovery. After the reset, Location Sevices keeps popping up for split seconds. And after a while, the screen would go white and show "loading launcher" and I could only mess with the notification toolbar. I reset it again and removed the sd card but it still does it. I hope someone here could help me.

I think try to reset the firmware OS see if the threats may occur again. Download on Acer website itself.

Another thing check your Playstore account first, cause the apps you download may install automatically which you can remove from the list.
