Stubborn Malware

Hi,

I am using Lava X11, I used to play many games and do some official work over my phone. All of my apps works well, but from few days I am getting a very strange problem step by stem below:

  1. It automatically starts downloading of games (these are from outside of playstore) sometimes it start in bulk.
  2. After completion of download - The option of allow installation from “unknown sources” turns on automatically (even I already set it off manually)
  3. It shows a dialog box from avast app that this content is malicious or dangerous to install (prior to installation)
  4. As soon as I turn off “unknown sources” option the installation cancels.
  5. Sometimes Avast pops up with infection alert “com.whatsapp.support…” or “com.cmsecurity.whatever…” by Agent-KTK or PUP… something like that…
  6. Whenever I resolve issue it turns to uninstall “com.applicationname.service…” that is infected by Agent-KTK or PUP…
  7. Then my problems temporary turns off for few hours…later it again start downloading…someday later it agains shows issue with “com.blahblah…” and again I have to uninstalled it…

To resolve this issue I did:

  1. Cleaned all cache
  2. Deleted unnecessary files and folders
  3. Scanned for “Ghost Push Trojans” but found nothing…
  4. Uninstalled doubtful apps…

Now I am using only few games like COC, COR, Candy Crush, Boom Beach… Apps like Whatsapp, Messanger, FB, Youtube, Office suit, Beautify Plus and other important and default apps…

I also scanned on offline antivirus of Avast and other companies but found nothing… >:( >:( >:( >:( >:( >:(

Now I am tired of this and I need solution keeping my all games, songs, videos, office apps and social apps secure…

Looking forward,
Nitin
