    This is a known issue in some recent Microsoft Defender Antivirus updates: Windows can show "Microsoft Defender Antivirus is turned off" notifications or provider status even when Defender is actually running correctly and all settings show it as active.

    What this means:

    • If real-time protection is on and scans are working, Defender can still be functioning normally.
    • The incorrect Security providers status can be a false notification, not an actual protection failure.
    • Microsoft has confirmed this issue and is working on a fix in a future Defender Antivirus update.

    A second possible cause is a non-Microsoft antivirus product:

    • On Windows 10 or Windows 11, if a non-Microsoft antivirus is installed and Microsoft Defender for Endpoint is not being used, Microsoft Defender Antivirus is automatically turned off.
    • If Microsoft Defender for Endpoint is being used with a non-Microsoft antivirus installed, Defender Antivirus starts in passive mode with reduced functionality.

    To check which case applies:

    1. Open Windows Security and confirm real-time protection is enabled.
    2. Open Services: select Search and type services or run services.msc.
    3. Check Microsoft Defender Antivirus Service under Windows Defender > Operational.
    4. If the service is set to manual and starting it shows a message like started and then stopped, that can indicate Defender was automatically turned off for compatibility with a non-Microsoft antivirus.
    5. If no third-party antivirus is installed and Defender is otherwise working, this is likely the known false notification issue.

    If the problem is only the incorrect notification/status, the current documented next step is to wait for a future Microsoft Defender Antivirus update. If needed, the issue can also be reported through Feedback Hub.
