Microsoft Defender Antivirus Notifications: A Temporary Glitch
Recent updates to Microsoft Defender Antivirus have led to an unexpected situation for users. Despite the software operating as intended and displaying all settings as active, notifications may still pop up, indicating that “Microsoft Defender Antivirus is turned off.” This anomaly can occur during the startup of Windows and may continue intermittently, even when notification settings are disabled.
This issue is affecting a range of systems, including:
- Windows 10 (versions 22H2, 21H2, Enterprise LTSC 2019, Enterprise LTSC 2016)
- Windows 11 (versions 26H1, 25H2, 24H2, and 23H2)
- Windows Server (versions 2025, 2022, 2019, 2016, 2012 R2, and 2012)
Microsoft has acknowledged the bug and is actively working on a fix, which will be included in a forthcoming update for Microsoft Defender Antivirus. However, a specific release date for this solution has yet to be announced.
Next steps: Microsoft has stated, “We are working to release a resolution in a future Microsoft Defender Antivirus update and will provide more information when it is available.”
