In reply to David.

The beef about McAfee is absolutely valid.

However, the rest of this comment is misleading. Viruses are most definitely still a threat to be reckoned with. As for Windows 11 PCs, Microsoft's built-in antivirus is decent (possibly enough for the average user) but still not quite as good/comprehensive as the top third-party tools, which, typically, also happen to bundle other useful security features.

So please do your homework before you conclude that your computer is immune to viruses it's fine to start clicking on mysterious attachments in emails and downloading random programs from random websites.
