    This task has been running at 90% to 97% cpu usage since I brought up my system 10 minutes ago.  Also Microsoft Antimalware gets turned off.  This is running on Windows 7 RC.

    This high cpu usage finally stopped.  I guess that this is the price to pay for this free software -;}

    Could it have been running a scan to cause the high cpu?

    No I was not running a scan.  I had just booted the system and was running ThumbsPlus application which takes little or no cpu.

    The most common reason for high CPU is a conflicting security program left in place before installing MSE. MSMPENG also consumes a lot of CPU when scanning. If you continue to encounter a problem with high CPU usage, please file a bug report.

    Similar problem here running Vista Home Premium. Usage is particularly high when opening another application, or even when opening a folder conntaining other applications.

    Thanks Stephen. I have an active report in. I have, by the way, uninstalled all other security products and have exhaustively cleaned the system of any traces of other security software. CPU use is still high -- frequently in 50 percent range -- though somewhat improved after cleanup.

    We had issues in the past (with OneCare) and msmpeng conflicting with some system drivers, so the bug report will be helpful. Thanks for filing it.
