    Hello. Can you please let me know if there is something in my HiJack log that would be causing firefox.exe (Firefox 3) to use 100% of my CPU? I have 3.5 gig of RAM and 2.8 ghz Dual core Intel. No idea why this is happening...

    Nope. Turns out there was some sort of an issue with the previous version of FireFox on the computer. I removed everything that could be associated with FireFox, and then reinstalled the software. Fixed everything.

    Thanks anyways!
