  1. Windows Defender Offline scan stops at 91%


    Ran Windows Defender offline this morning for no particular reason. I'm pretty sure machine is clean. Full system scan and Malwarebytes found no threats. It got to 91% then closed and restarted. Any idea why it stopped ?

    Last couple of lines in the log read:

    2021-02-07T19:44:28.880Z Service stop requested (ServiceError: 0x0). Calling CleanupMpService ...

    Thanks in advance for your help.

    I found the answer. mssWrapper log reads:

    INFO2021/02/07 11:44:28:864 TID:1364 PID:1332
    Scan completed successfully, attempting to clean any active malware. Number of threats from scan: 0

    All good. Marked solved.

    Defender Periodic Scanning or Offline Scanning?

    That link does suggest it's useful to use Defender offline scanning in addition to periodic scanning and a third party real time anti virus (e.g. Kaspersky).

    offline scan by win defender

    Hi,

    To further assist you with your concern with Windows Defender, follow the steps below:

    • Open the Run window by pressing Window + R button.
    • Then type services.msc and hit "Enter".
    • Look for Windows defender service in the list and right click on it and select start.
    • Once Windows defender is opened try to do the offline scan on that window.

    Let us know how it goes.

  4. Windows Defender Offline scan stops at 91%

    Windows 10-Microsoft Defender Offline scan stop at 91%, PC reboot then

    As in the title. I run the scan, it scans circa 55000 files, stops at 91%, the black window dissappear, there's only blue background, and the PC reboots. I have all windows updates, i ran sfc /scannow i ran DISM scanhealth command and everything is fine. I've ran chkdsk and it's also fine.
