How to detect, and stop fake virus notifications and phishing notifciations and spam notifications on Mac OS.

Apparently, I recently accepted a website’s dialogue that asked for notification access. I suspect this happened while using some free services to convert YouTube videos into MP3’s and converting MOV to MP4 files.
