Rundll32.exe and Pop-ups problem. Hijack log included

Hi.
I've run Ad-aware SE, Spybot Search and Destroy, and Norton Antivirus 2004 (with Norton Internet Security) multiple times in both normal and safe modes in Windows XP Professional SP1.
The problem is that whenever I open a new internet explorer window, more pop-ups come up or when I enter an invalid URL.
The other problem is that when I use my computer for a few hours, Internet Explorer stops loading any URL i try to go to. Then when I look at what's going on in the tasklist, Rundll32.exe is @ 100%. I try to close the rundll32 process, but Internet Explorer still doesn't work. I have to reboot in order to get it to work again.

Here's my Highjack log. Please let me know what to fix or what else I should run to fix the problems.

The only thing I'm able to identify here is bridge.dll

... this is a IE favorites hack and may be providing some of the pop-ups. You can remove this <a href="http://securityresponse.symantec.com/avcenter/venc/data/adware.winfavorites.html">HERE</a> for removal instructions.

As for scanning for any other spyware, I've actually had a LOT of success with Spy Sweeper over any other program. Go <a href="http://www.webroot.com/wb/products/spysweeper/index.php">HERE</a> and download Spy Sweeper. You don't need to buy it.

Try scanning with that and post your HJT log after that.
