- Windows 11's antivirus is bugged as of the latest updates
- Microsoft Defender is telling users that it's turned off, when in fact it isn't — it's working just fine
- The warning keeps popping up, though, and that's proving to be frustrating, although Microsoft is now working on a fix
If you use Windows 11's built-in antivirus and you keep getting worrying messages warning that it's turned off and you're no longer protected, the good news is that this is a bug, and you've got nothing to be concerned about.
