    unable to open windows settings or turn on windows defender


    I recently tried to install a mod for a game i was playing and well, it was a virus. I deleted yet i still can't turn on windows defender and when i try to open any settings it closes the window. I resorted to a full system restart and yet again, closed it right away. I can't open chrome and the laptop has been really slow. I don't know what to do and any help would be great. Thanks.

    :)

    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:
    Let your Windows 8 Defender update itself automatically.

    Unable to turn on Windows Defender real time protection


    Hi guys, I'm a bit desperate here right now. *Confused

    I have the same problem that this guy over here. I'm running Windows 10 Home x64, version 1607, build 14393.0.

    I had to restore the PC to a previous point because I ****ed up some drivers. Then my AV (Bitdefender Free) started having some issues (they gui didn't display correctly) so I decided to uninstall it and just go with Windows Defender.

    The problem is I can't get it to work... I get a notification in the Action Center saying to turn on the virus protection, when I click it, Windows Defender goes green(PC status: protected, Real time protection: on) for a second and then goes yellow again (PC status: Windows Defender is OFF, Real time protection: Handled by another AV program) and I get the notification again. If instead of clicking the notification I click "Turn on" on the Windows Defender gui, Windows opens another window, "Apps & Features" in settings, like asking me to uninstall the other, nonexistent AV.

    Now, I've tried a lot of things...


    • Of course, I have completely uninstalled Bitdefender. I used the official tool provided by them for this. There is nothing in the registry by bitdefender nor any file or folder by that name in my PC.

    • I have tried every step listed here.

    • I have tried to install another AV (Avast) and the uninstall it to see if this would "reset" somehow windows defender. (Nope.)


    • I have run MBAM and nothing pops-up

    In HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender there is noDisableAntiSpyware key. But in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender there is a DisableAntiSpyware key and its value is 0. (Not sure if this is important but wanted to give you the info.)

    Anyone has any idea? Right now I'm thinking of downloading another AV or just go without any and be done with it. *Huh
