    Whenever I try to open windows defender antivirus it tells me that my system administrator blocked it, but I don't have one. When I try to activate through settings, I just get an error message. This just started happening even though I made no changes. Could this mean I have a virus? Any help would be appreciated.

    :)

  2. Windows Defender problem

    Hi Ernst,

    To troubleshoot this issue, we suggest that you check the Windows Defender service if it's running. If you are using a third party spyware/malware program, it may disable the Windows Defender service. To do this, please follow the steps below:

    • Press Windows + R key.
    • Type services.msc.
    • Right-click Windows Defender service and click
      Start.

    Let us know the result.
