I keep getting notifications, supposedly from Mozilla and/or Microsoft on lower right of my screen, telling me the system is infected. How do i determine if these messages are valid, or a scam ? Turned computer off and back on--messages keep popping up.

Hello,

Firefox does NOT send such kind of messages. Do they show up when Firefox is closed?

Also, could you please post a screenshot of those messages? What do they prompt you to do / where do they lead you?

These are popping up all over my screen. trojan detected, virus detected etc. Please tell me how to remove them

Hey patzanddennis,

Try blocking Web Push notifications in Firefox for suspicious websites. Also, if you need further help, please [support.mozilla.org/questions/new/firefox/form ask a new question] (and make sure to read the answer above!).
