  1. Windows Defender - Full scan - Take action on threats


    After running a full scan, some threats were reported. "Taking action" has now been in progress for several hours.

    Is this normal?

    How long can it take?

    what happens if I terminate it by closing the window?

    :)

    Windows Defender keeps taking action on nonexistent threats on nonexistent scans

    I have a laptop (Dell Inspiron 3541) running Windows 10 v1803. Recently, I have been getting notifications from Windows Defender saying threats were found and removed on scnas that didn't happen.

    Some of the notifications are:

    and

    When I go to Windows Defender, it doesn't show any threats found - nor does it even show a recent scan. For example, I got one of the above notifications today, and this is what Windows Defender showed.

    I tried running a scan, but the ETA was 4 hours, then 20, then 70, and still kept going up.

    Is there a way I can find out what the "threats" are? Or make it stop sending these unnecessary notifications?

  3. Defender finds a threat but doesn't take action

    I ran a full scan and defender seems to have found a threat but when I say to fix it, it runs forever saying it is "taking action on the threats". When I select "See threat results" it shows no threats. Did it or not find a threat?

    Windows Defender - Full scan - Take action on threats

    Windows Defender keeps taking action on nonexistent threats on nonexistent scans

    You may turn off some notification options in
    the Windows Defender Security Center, section
    Virus & threat protection. Click
    Virus & threat protection settings,
    scroll down and click
    Change notification settings, then disable the ones you don't like.

    I have solved my problem of dummy popups as described below,
    without changing the notification settings.

    Again in the Windows Defender Security Center, section
    Virus & threat protection, click on Threat history.

    Do not be misled by the message of "No threats".
    Click on both links of See full history, which may show some items.
    For each items click See details to check which file it is, and if
    not a threat then click Allow.

    After this Defender will calm down, although there will still be
    one notification in the Action Center.
    If it bothers you, turn it off as described above,
    but it might still be useful.
