Sorry to hear that. But these rogue antivirus stuff is very hard to detect. There are many rogues everyday and most of them are unique. Since they are not doing malicious stuff, they are hard to detect by the security suites.

For the cleaning part,

  1. Please download malwarebytes antimalware from here.
  2. Install and update to the latest database.
  3. Run a quick scan, remove all infections found and reboot if required.
  4. Post the log back here using the additional options while posting.
