Stop unwanted Notifications

Phony "tech support" / "ransomware" popups and web pages

I also get this and I have no idea how it started happening. Do this though:

If you're receiving desktop notifications on Safari from an unknown website, it means a site you visited recently has likely requested permission to send notifications, which you might have accidentally allowed; to stop these notifications, go to your Safari settings, navigate to the "Websites" tab, then "Notifications" and block the specific website causing the issue by selecting "Deny" next to its domain.
