    Defender wants fast scan after every restart


    I boot the computer running Windows 10 x64 DE 2004.

    I am logged with MS account and administrative rights.

    Defender Engine is 4.18.1909.6


    In infobar the defender security icon schows an exclamation mark, it recommends a fast scan.

    I open defender and proceed the fast scan.

    Defender security icon shows green checkmark.


    I reboot the computer.

    In infobar the defender security icon AGAIN schows an exclamation mark and recommends a fast scan, although i have scanned few minutes ago.


    I open defender and it sais: last scan - not available.

    defender 'forgot' that it scanned just few minutes ago.


    Where does defender store the scan history?

    Are there any services needed to be running to store this information?


    Can i repair this myself or is an update needed?


    regards

    Max

    :)

  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.
