My Android seems to be infected with a very nasty virus. Sometimes when I open links to totally safe pages (like stackoverflow) from my mobile I got redirected to a page called adfoc.us (adfoc.us/serve/?id=25497650908175) that then tries to download files like MoboMarket.apk that seem to be malware.
I tried running MalwareBytes but it only detected the .apk files that were downloaded. I tried running Avast, but I did not detect anything.
What else can I do to solve this problem?
