  1. Defender is the only app that detects it. But it wont remove it using remove or quarantine. It seems to be attached to an adblocker in Mozilla.

  2. Its only defender that says its a threat. It looks like its attached to adblocker on Mozilla. Remove and quarantine does nothing the only thing that works is “Do not allow”. I’ve tried several antivirus and Microsoft’s Safe Scan app. I did get another virus from installing “Uninstall” from Iobit, but I could quarantine that one. I don’t get it at all.
