Help!!! Can't open IE, CPU spikes to 100%

[tspencer1234]

This is my first posting and I'm desperate for help. I can't open my IE browser (the status bar doesn't even get half way across). My CPU usage spikes to 100%. I've run spybot, ad-aware, mcafee but nothing shows up. I've looked all over the web for a solution but haven't found anything. Earlier today I was able to get it to open (but only once). It happened after I went to internet options, advanced, and unchecked the "enable third party browser extensions".

I'm running XP home edition from a computer with 512 RAM and 80GB hard drive.

Here's my hijack log:
