I literally just cancelled my McAfee subscription because of annoying constant pop-ups like this. At least this one from Microsoft is a legal notice. McAfee constantly spams you to turn on unnecessary features, and even changes settings periodically to turn things on like “browser monitoring”. Literally worse than old school pop-up viruses.
More importantly, it also never caught a single thing. Windows Defender does fine. My buddy in cyber security suggested them for safety despite how bad they are, but I can honestly recommend you should never, ever, get it. Just keep backups and be prepared to nuke your system if needed, and save yourself a pop-up every other day.
