    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.

    How to fix full av scan failure in Microsoft defender 365?

    Windows defender ofline scan

    Peter,

    Event viewer maintains a record of the scan starting at

    Application & service logs,

    Microsoft,

    Windows,

    Windows defender,

    Operational,

    Event IDs 2030, 5007

    • WDO failures that Windows knew about would be recorded as EventID 2031
    • but WDO failures while Windows was not running would not be recorded.

    But there is no record of its completion unless it finds malware detections to report in

    Windows defender security centre,

    Virus & threat protection,

    Scan history.

    • The Last scan entry in that dialog refers to Windows defender itself not WDO.
