    Windows Defender auto closes after ~5s


    I click the tray icon or execute it through start menu, after a little while the window closes. But it is still running. Ideas?

    icetbr,

    Welcome to the Forum!

    Have you run the System File Checker (SFC} to see if there's something amiss?

    (use Option 3: This option scans the integrity of all system files and repairs files with problems (ex: corrupted or modified) when possible.)

    If files need fixed, you can use the following:

    Hi, thanks fr the suggestion. Yes, I have tried that, it shows no errors. Should I go for the other options in the page you suggested? Dism /Online /Cleanup-Image /RestoreHealth and others.

    Please clarify. You execute a scan and then the WD window closes but the scan is still in progress ? You then click the WD icon in the taskbar ?

    If you are opening another tab or program, that is normal if the scan is being completed.

    icetbr,

    If sfc /scannow did not find any corrupted or modified system files, if you wish, you can use the CheckHealth or the ScanHealth command to conform status.

    After reading, torre's post, maybe I am misunderstanding the issue. Please clarify, as requested. Thanks!

    Note   Note
    If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command up to 3 times with Fast Startup turned off and restarting the computer after each time to completely fix everything that it's able to.

    If not, then run the Dism /Online /Cleanup-Image /RestoreHealth command to repair any component store corruption, restart the PC afterwards, and try the sfc /scannow command again.

    If still not, then you could refresh Windows 10, or do a system restore using a restore point dated before the bad system file occured to fix it. You may need to repeat doing a system restore until you find a older restore point that may work.

    No, I can't do a manual scan (when it closes the scan is canceled), it is running because it says it is active, and it finds threats, and cleans them.

    I will try the other suggestions and report later

    Well, short of restoring, so far nothing worked. I think I'll refrain from doing that in favor of a 3rd party antivirus for the moment. Avira and malwarebytes found no problems.
