    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.
