    Recently I have noticed after rebooting my computer msmpeng.exe will run using over 90% of the processor. This will continue for several minutes and I'm not able to do anything. Research shows that this is related to Defender, but I'm running MS Security Essentials and Defender is not installed on my PC. Is it related to Security Essentials and is it anything I need to be concerned about. I also ready that it could be a well disguised virus, but I ran several virus scans and they all came up clean. Thank you for your help.

    It is also part of MSE (one reason why MS says not to have both MSE and Defender).

    Thank you. Defender is not installed, so it's MSE. Since my initial post,
    I found that it also runs on my other XP computer after rebooting, but it's
    not as noticeable because that PC has faster, multiple processors and
    msmpeng is consuming a little more than 20%. The PC in question has a
    single, slower processor and msmpeng is consuming around 90%. Thanks again
    for your response. I feel better and will assume that msmpeng.exe isn't
    anything I need to be concerned about.

    When (approx. date) did you install Microsoft Security Essentials (MSE) and
    was the computer fully-patched at Windows Update at the time?

    What anti-virus application was installed before you installed MSE, was your
    subscription still current, and did you uninstall it before you installed
    MSE?

    Has a(nother) Norton or McAfee application ever been installed on the
    computer?

    Did a Norton or McAfee free-trial come preinstalled on the computer when you
    bought it? (Doesn't matter if you never used or Activated it.)

    I installed it about 6 months ago and the computer was fully-patched at the
    time

    I was using McAfee downloaded from Comcast before I installed MSE. The
    subscription was current and I used the complete uninstall instructions and
    tool supplied by McAfee via Comcast before installing MSE.

    Norton was installed, but I used the uninstall instructions and tool from
    Norton via Comcast before installing McAfee. See above regarding the McAfee
    uninstall before moving to MSE.

    Norton was installed and I later upgraded it to the full version. Norton
    then ran on the computer for several years before installing McAfee.

    Thanks for your help

    Please confirm that you run the Norton Removal Tool and the McAfee Consumer
    Products Removal Tool prior to installing MSE.

    If you've got further questions about MSE, please post them here:
