I have a generic android tablet running Android 4.4.2 with the Atom shell and there are some apps and media files that I keep removing that keep reinstalling themselves, and there's something that keeps spamming ads on my screen. One thing is doing full screen ads and when check the screen showing all apps that are running, the big ad is under something called "Tasks" with the android logo as an icon.
The apps that keep installing themselves are:
Something called "Settings" with a green baseball diamond looking thing with a red exclamation point that is clearly a fake settings thing.
and a video called MP4(800x480).mp4
Also I have tried booting the tablet into safe mode using both methods, (Holding down the power button for a few extra seconds, as well as the method of booting while holding down both volume buttons), and neither work.
I'm a bit new to Android so I don't even know what are good anti-malware/adware apps. I use a combo of Spybot Search & Destroy + Ad-Aware on my windows computers.
Any help would be appreciated.
