    Defender reports a lot of files when I am scanning a usb drive


    Using the custom scan, the Defender reports more that 50000 files. Sometimes the custom scan finish, sometimes no. When I am scanning the same usb with Crowdstrike or MalwareBytes I have 300 files. Any suggestion? or explanation?

    :)

    Windows defender custom scan does not scan external drives

    I tried the custom scan in Defender Windows 10. It brings up the list of drives but the "OK" button remains grayed out when I select any drive in the list, so still unable to scan external drives... Any suggestion would be appreciated.

    Windows Defender scanning USB flash drive in the background

    Hi guys,

    Whenever I stick my USB flashdrive in my notebook, for some reason it will not paste my files there. The progress bar just says 0% when copying from my Documents folder and pasting to the USB stick. But sometimes. Especially when I leave the USB stick in for several minutes. And these are not huge files.

    My assumption is, that its got to do with Windows Defender taking over the USB contents and scanning it and when its scanning the contents of it, it will prevent writing to the USB flash drive. Now, not saying that this is true, but I do have a strong feeling. And sometimes, it will have a delay to safely remove the USB flash drive as well.

    So my question is, is there anything that I can do to prevent this from happening?

    The scanning of removable drives is DISABLED or NOT CONFIGURED in Group Policy, so I have not even touched that.

    How can I prevent the scanning thats happening automatically in the background without actually disabling Windows Defender?

    What I can perhaps do, is adding the USB drive to the Exclusion list.
    For example, adding D:\

    Or maybe its scanning the Documents folder?

    Any other suggestions?

    Thanks
