Short bio

This is a generic detection for a special kind of Trojan that changes users’ DNS settings on his system and that it require some actions to undo the changes:

  • Reset the DNS settings to something safe
  • Clear the browser cache
  • Remove the jobs (Scheduled Tasks) that were responsible for the change (if still present)


Malwarebytes can remove these threats completely without any further action of the user. A reboot of the system immediately after threat removal finishes is required though. And the user will be prompted to do so.
