  1. Unable to clear protection history


    I am using Windows 10 Home build 1909 and I am unable to clear the Windows Security Protection History...


    I have tried...


    Open Event viewer and find Log "Operational" under Application and service logs / Microsoft / Windows / Windows defender
    Right click on it and select clear log.


    and


    Delete folder Service C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service .

    After deleting the folder Service, off and turn on OFF>ON Real-Time protection and Cloud protection.


    And neither suggestion works. Are there any other suggestions to clear the protection history


    Microsoft needs to reinstall the clear button.


    I have entries because I had Controlled folder access turned on by accident... I have it off now.

    :)

    Clearing Windows Defender history

    Hey, what you need to do is so simple, just follow the steps below exactly in order:
    1. Turn OFF Real-time Protection
    2. Turn OFF Cloud-delivered Protection
    3. Go to this folder C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service
    4. Delete the contents in the folder
    5. Turn ON Real-time Protection
    6. Turn ON Cloud-delivered Protection
    That's it... Now check protection History, it's empty.
    Done!

  3. Clearing Windows Defender history

    It appears I might have discovered a little "chink in the armour" as this method doesn't seem to work IF you have any detections listed in the protection history from the controlled folder access feature... if enabled.

    Clear Windows Security Center (Defender) Protection History

    While Windows Defender can be configured via Powershell cmdlet "Set-MpPreference" thus changing Group Policy and Registry settings to purge after 1 day minimum, however, this fails to accomplish the objective which is to clear the protection history manually and/or instantly as this topic suggests.

    I tried this with no success... even tried rebooting to make sure at no avail.

    This is the procedure that does indeed work.
    I previously had tried deleting the folder before with no success but turning off, then on said protections is what apparently allows this to work. Thank you and the OP "LiNer2" from windows forum for this.

    To anyone who wishes to try this and you don't happen to have any current protection history...
    you can utilize the "EICAR Anti-Malware Testfile" to check the solution.
