system blocked by intruder
I am running an iMac that is about eight years old.This afternoon my Firefox browser was taken over by a "warning" from "MacOS security center" that I should go to THEIR macOS support site to get my system unfrozen. The number they give is 1-877-xxx-xxxx. I cannot get this intruder to go away, even by restarting the computer.

Further to this, have you installed any add-ons recently or perhaps other apps on your device?
