Help Malware / Virus in my Android Tablet

[ePLayar]

Hi all,
I'm new here so I hope I didn't post in the wrong place.
So I have an Android tablet : Samsung Galaxy Tab 2 10.1

Some days ago I installed some Gift Card app, one of those where you have tasks like watching videos, installing apps, trying out games etc...

I did install couple of them and I think one of them had a malware in it or something, because since then, my tablet installed bunch of apps randomly and I keep getting weird white screen with "launcher loading" on it every time I go online.

I tried to reset my tablet twice but, I still have problems, every time I go online I get this "launcher loading" white screen for couple of seconds, and then i get a black screen with a menu on top that says Services that stays there for some time before it disappears, not only that but if I keep my tablet online, it installs random stuff that I can't find in the apps menu, only shortcuts on the main screen, random stuff like "Demo, Demo, Facebook, Sex Club".

My tablet also restarts by itself if I stay connected to the internet and resets the language to German from English.

I really need help fixing these problems, any help would be appreciated. Thanks!

If a Factory Reset will not correct the problem, you could try flashing the stock Firmware.
Factory Reset should work unless the system is corrupt then a reflash would be necessary.
What is the complete model number?

How to flash the stock Firmware?
The model is : GT-P5100

Create a free account at Sammobile. Free download is slow but best place for stock firmware.
Select the correct firmware for your country and carrier and download.
Instructions for flashing are located at bottom of download page
