Okay. I've done everything ... and I mean everything on
this list. ;-) Each morning, I run the 5 spyware killer
type programs (the first 5 on your list) However, I'm
still having the same problem. 100% CPU usage w/ the
culprit being rundll32.exe. What the heck does
rundll32.exe do? (it doesn't seem to be killable in the
taskmgr)

Any other suggestions?

Thanks again!
