Help Virus

[erikolenju]

I have problem with my prestigio with android 4.4.2
I have the engriks virus but i cannot remove it because i cannot install apps from store or apks. Everytime says app not installed.
Everytime i switch on my phone installs lots of garbage apps.
Also my storage keeps saying calculating maybe theres the problem why i cant install nothing

Could be worth trying a factory reset.

Is the phone rooted? If so, you might need to re-flash the original Prestigio firmware.
