CPU pegs at 100% after closing IE

After struggling with a 100% pegged CPU for several days, I was able to consistently reproduce the problem by simply closing IE.  I noticed there was still a process running called IEXPLORE; stopping this process brought the CPU back to normal runtime levels.  The problem sometimes occurs when I haven't closed IE and at those times there is no IEXPLORE process running.  Nothing I can close from the Task Mgr fixes the problem when it occurs like this.  In the process tab of Task Mgr it is SERVICES that is showing all the CPU use.  The problem seemed to start when I downloaded and attempted to run a VPN application.  I don't really think that program infected me, it came from a reliable source and I only discarded it because it would not penetrate the firewall at my jobsite.  It is possible the app changed some files or settings...(?) maybe unrelated  

In troubleshooting I have already done the following:

Removed the recently installed app (of course)
Current with all critical W2k updates
Current with Norton AV
Ran full scan with AV
ran CWSHREDDER to remove CoolWebSearch
loaded and ran SPYBOT, removing all offending apps it found
ran HijackThis and fixed all annomalies that program found

These steps fixed a number of other annoyances I was experiencing, but did not address the CPU issue.  Unless I come across a better idea, my next logical step is to format C: and reload W2k

Any thoughts would be greatly appreciated,
HR
