    Hi Mary,

    As per the issue description you are unable to scan your computer using Windows Defender. While scanning your system you are getting an error message "Your PC couldn't be scanned. This program's service has stopped. You can start the service manually or
    restart you computer, which will start the service."

    The issue could be if the service responsible for Windows defender either get corrupted or is stopped. Try the steps provided below and see if it helps you to fix the issue.

    • Press Windows key + R to open run box.
    • Type services.msc and hit enter.
    • There should be 2 services: Windows Defender Service
      and Windows Defender Network14.
    • Right click on each service and start the service if not running.

    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.
