Recently whenever I open Firefox I get a message in notification center. It's not always the same and it keeps changing. here is an example:
It's not always this. It gives other messages too and when I click it it sends me to phishing sites. I don't know how I got it.
Could someone please help me get rid of it?
I tried Clam antivirus but it found nothing.
Keep calm, it looks like a mere phishing attempt with FUD. It seems some website(s) somehow tricked the user into giving permission for push notifications.
To fix this, follow the steps below.
