    Can't run Windows Defender Offline


    When I attempt to run Windows Defender offline, first I get the following window:

    "Save your work - Windows defender offline scan will take some time ----etc."

    I select SCAN and get the following window: "Do you want to let the app to make changes --- etc."

    I can wait at least a half hour and nothing happens.

    When, POWER-RESTART the system boots normally.


    About System:

    Windows 10 Home - Version 1909 - build 183563.1316

  2. Running windows defender offline

    Hi,



    Thank you for writing to Microsoft Community Forums.



    We understand your concern as you are having some unusual activity while running the Windows defender offline scan. In order to get clarity and to assist you accordingly, please reply with the answers to the questions below.



    • What is the make and model of the PC?
    • Do you see any error message before the blank blue screen?
    • Do you get the blue screen every time, when you run Windows defender offline scan?


    To identify the root cause of the issue we need to analyze the dump files located in
    C:\Windows\Minidump as you are getting a blue screen before restarting the PC, please upload the dump files on OneDrive and share the link with us.



    However, if you want to run the Windows defender offline scan again, then we would suggest you to put the PC in software clean boot, refer the article

    How to perform a clean boot in Windows
    . A ‘clean boot’ starts Windows with a minimal set of drivers and startup programs.



    Note: After you finish troubleshooting, follow the section
    Reset the computer to start normally after clean boot troubleshooting
    to reset the computer to start normally.



    Let us know how it goes.

    Windows Defender Offline for Windows 10

    Tried this suggestion and it did not work. Tried to boot from USB with Windows Defender Offline transferred from a safe computer. Would not boot from USB. Message "Secure Boot Violation, Invalid Signature Detected, Check secure boot policy in Setup"
    Any suggestions on next steps for a Windows 10 compatible version of Windows Defender Offline?

    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.
