    Hi Mina,

    It looks like you had some trouble deleting DetectionHistory as the history is still there.

    To resolve the issue use one of these methods to delete it:

    Method 1

    First boot into safe mode:

    Delete the DetectionHistory folder from:

    C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service\DetectionHistory

    Restart your computer.

    Note: To see the ProgramData folder and subfolders,  make sure you are showing hidden files and folders.

    • Windows 10: In File Explorer, select the View tab > check (tick) Hidden items
    • Windows 11: In File Explorer, select View > Show > check Hidden items

    Method 2

    Use the tool I wrote specifically to delete detection history. There's no need to boot to safe mode, just unzip, run and restart.
