This happened to all my machines.. there is something wrong with the
Malicious Software tool update... After this update is installed the CPU will
go to 100% and the process that is doing it is the Malicious Software tool..
(I forget the exact process name.)

I am trying to get it to work properly on one machine without success, on my
other machines I had to Restore the system back to yesterday to get the
machine to work properly.

Looks to me like there is a problem with this update.
