  1. Problem with running and Updating Windows Defender


    I have Windows 8.1 and am trying to turn on Defender. I have no other virus protections downloaded. Under Updates, any updates for Defender were always CANCELLED. Here are some error messages: 8024000B - KB2267602-version 1.307.1571.0. I've read every solution out there but none of them worked. I believe I turned it off a few years ago. I read that perhaps it can not be turned back on. Any advice will be appreciated. Thank you.

    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:

  3. Windows Defender problem

    Hi Ernst,

    To troubleshoot this issue, we suggest that you check the Windows Defender service if it's running. If you are using a third party spyware/malware program, it may disable the Windows Defender service. To do this, please follow the steps below:

    • Press Windows + R key.
    • Type services.msc.
    • Right-click Windows Defender service and click
      Start.

    Let us know the result.

  4. Problem with running and Updating Windows Defender

    Windows defender's process running despite it being disabled.

    Windows Defender is integrated within Windows 10. So you have it and it is running (as it should be) unless you installed a 3rd party "real-time" anti-malware solution. If you are using an alternative security solution, it should have registered itself with Windows Action Center which would then disable the real-time component of Windows Defender - unless you specifically told the 3rd party solution not to register itself.

    For example, if you purchased Malwarebytes "Premium", it has a real-time scanner (the free version does not). When you install Malwarebytes Premium, it registers itself in Windows Action Center. But because Malwarebytes and Windows Defender play very well together without hogging resources or causing conflicts, it is often recommended to allow each to run at the same time. So to allow that, the user has to manually go into the Malwarebytes control panel Settings menu and select the option to "Never register Malwarebytes in the Windows Action Center".

    I suspect other 3rd party solutions provide similar options so you might check that out if you did indeed, install a 3rd party security solution.

    Both Windows Update and Windows Defender are supposed to step way back in to the background so they do not interfere with system performance when you are actively using your computer. But this is not always possible, especially if you regularly shut down your computer when you step away from it (instead of just letting it go to sleep), as too much time may have passed and your system is too far behind in Windows and security updates.

    Without you noting which program was actually consuming the lion's share of that 80%, there's no way to tell what, at this point, was causing the problem. However, I would not put it past a browser. Chrome, for example, is very good (or bad, I should say) at eating up a lot of RAM and failing to let it go when exited.
