    Windows defender automatically turns itself off


    Hello, my store app crashed after updating apps and I couldn't fix it for a day, whenever i tried to re sign it using powershell it said my firewall was off, I checked to see that no matter what I did, I couldn't turn it on so I decided to reset my pc, but after a couple of hours it disabled the anti virus and firewall by itself and I can't turn it on no matter what, I dont use any antivirus software other than win. defender, i tried regedit and services.msc to enable it but to no avail

    :)

    WINDOWS DEFENDER is turned off

    Hi Ahmed,

    Since you're not able to turn on Windows Defender as well, we'd like to know if you have made any changes recently prior to this issue. In the meantime, you may follow the steps below on how to turn on Windows Defender manually:

    • Type Windows Defender in the Search bar and press
      Enter.
    • Go to Settings and make sure that the Turn on real-time protection recommended option is turned on.
    Same thing with the other members who are having the same issue, we suggest that you check if the service was setup to
    Automatic in the Services option. Please follow the steps that we've provided last
    September 3, 2017.

    Let us know how if you were able to turn it on properly by changing the Startup type to Automatic.

    SEtting up automatic updates for windows defender on windows 8

    I have found this on the internet en have set up a task for automatic definitions update for Windows Defender but a window pops up when this starts to run.
    Is there a way to set this without any window popping up so that it just runs in the background?

    Now I'm using
    "C:\Program Files\Windows Defender\MpCmdRun.exe" -SignatureUpdate -MMPC

    I'm currrently using it as described here:

    windows defender turned off.....................

    @atramsuraj: You can
    read this post     and follow the given steps to re-enable your Windows Defender. And, by the way:

    • What OS are you running?
    • Are you also using 3rd-party security program? If so, please consider disabling it, as some could turn off Windows Defender automatically.
