  2. defender scans

    Hi Ian,

    Thanks for posting your query on Microsoft Community.

    This issue might occur if you have set any task scheduler for Windows Defender.

    I suggest you to delete the task for Windows defender and check if it helps.

    Follow the below steps:


    • Search and open Schedule tasks.

    • In the left-hand menu, open the Task Scheduler Library, then select
      Microsoft >Windows >Windows Defender.

    • Double-click Windows Defender Scheduled Scan.

    • Select the Triggers panel, then select Delete.

    Hope it helps, reply to us with the status of your issue. We will be happy to assist you.

  3. WINDOWS DEFENDER is turned off

    Hi Ahmed,

    Since you're not able to turn on Windows Defender as well, we'd like to know if you have made any changes recently prior to this issue. In the meantime, you may follow the steps below on how to turn on Windows Defender manually:

    • Type Windows Defender in the Search bar and press
      Enter.
    • Go to Settings and make sure that the Turn on real-time protection recommended option is turned on.
    Same thing with the other members who are having the same issue, we suggest that you check if the service was setup to
    Automatic in the Services option. Please follow the steps that we've provided last
    September 3, 2017.

    Let us know how if you were able to turn it on properly by changing the Startup type to Automatic.

  4. Can't turn on,scan or any other thing through Windows Defender

    Windows Defender for Windows 10 will not turn on for Occasional Scanning

    Windows Defender for Windows 10 will not turn on for Occasional Scanning on my PC. I have WebRoot SecureAnywhere for as my main antivirus software. If I change the settings in Windows Defender Security Center to turn to Occasional Scanning to ON, and Click
    OK in UAC, as soon as I do that, Windows Defender Security Center Occasional Scanning turns OFF.

    Does anyone have any suggestions on how to fix?

    Thanks.
