I'm not sure if this is a problem in 2010. But form the task manager it looks like you have zone alarm.  Zone Alarm has been known to have software conflicts with other programs. My family used to use Zone Alarm and would always experienced software problems not with zone alarm but with other programs running.  My family took zone alarm off and the number of programs freezes and crashes were greatly reduced.

Zone Alarm might be causing the problem especially if you are noticing that other programs are freezing or crashing. You can do a google search and read about the software conflicts that zone alarm is known for having.
