Firefox Community Forum

I've suddenly started getting continuous pop-up notifications warning of a virus, a trojan virus, system alert, etc. Some mention McAfee (I use Total AV and have run scans and it says there are no problems). THese bitufucatuibs sat they are coming from Firefox. They are just constant and even when I delete them they just keep coming. What's going on?

'Dear Customer Support, I use Firefox exclusively as my browser. I use Google Calendar as one of my tags. For a few weeks, a number has shown up to the left and I want to eliminate it. I was referred back to you for help by Google and told it was a listing for “motivations/notifications” and could be “shut off.” I could not even find a listing for “motivations” among the Firefox listings. I would appreciate your help in finding a way to block this number on the Google Calendar tag. Thanks.'
