I think I have a solution. Well, it worked for me.

  1. Uninstall your Avast! Antivirus.

  2. Download the trial of the version 4.8 (this is important, because this virus is newer, and can easily go trough avast 6 protection.

  3. Go to C:/Windows/System32/drivers/etc/ and delete hists. (I dunno what that is but I don’t care, because it’s called hists.

  4. Set your file options to see hidden files.

  5. Delete a file named hosts. (If you like to explore, look inside of it)

  6. Try to search for a default hosts file to download, if not, download mine:

After all this, run a boot scan with the 4.8 , and when done, install Avast! that you previously had.

This did it for me, especially because it wanted to pop-up some ads.
