msmpeng.exe running at 95% cpu usage

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.

Answer
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.
