MsMpEng.exe Hell

MsMpEng.exe is the antispyware component of Microsoft Defender antivirus software suite.  It's also part of the commercial Microsoft ForeFront antivirus software suite.

I run a Intel Core i5 M520 dual core processor running at 2.40 GHz, however, when MsMpEng.exe kicks in, the CPU utilization spikes to 100%.  The system becomes completely unresponsive until MsMpEng.exe completes.
