Running Big Sur 11.5.2 -- I get the red x and error message " Your Mac is at Risk from Viruses and Spyware, Fix Now" -- the 'Fix' mode and 'Scan ' mode continue for days, placing files in quarantine, but never fixing the issue. This has been going on for a week now. I've restarted and reinitiated, but no resolution. Live Update continues to work without issues.
I have asked this thread be moved to the Mac board for better exposure.
