Supposed virus notification from Mozilla Firefox

I'm getting announcements of a virus threat that purports to come from Mozilla Firefox. Usually one or all three of the attached small windows that say: 1. "Viruses Found. Antivirus notification. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 2. Attention! Click here to secure your data!. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 3. "System Warning!. Click here to remove them! via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. I have run full scans and offline scans with MS Defender, but these warnings still appear. Is this legit? I suspect these are a virus of some sort. Either way, how do I deal with this?

Hi

Have you installed any other apps on your device recently?

If you clear your browsing history and then do a second scan, do these alerts still appear?

These appear to be web push notifications from sites you have allowed to send you notifications. Instead of useful information some may send you junk, spam, fake virus/trojan alerts etc. You can revoke these sites from sending you notifications as second kb link above shows.

Many thanks to Paul and James. I did both of your suggestions, and so far the notifications have not reappeared. Fingers crossed.
