Error Loading C:\windows\system32\bridge.dll

That log looks great...so how did you finally clear the entry? Manually edited the Registry or other method?

Special Comments:

I would stop the P2P client from Autostarting...start the program when you need it, don't leave yourself wide open all the time:

Fix check:

O4 - HKLM\..\Run: [P2P Networking] C:\WINDOWS\System32\P2P Networking\P2P Networking.exe /AUTOSTART

Also fix check the following 016 entries for your IE ActiveX scripts...It is good to clean out an excessive number of ActiveX scripts. They are easily restored when you visit that URL again if you know it is safe and accept the download of the expander or .CAB file. I'm beginning to recommend a thorough scrubbing now in this area...even a valid ActiveX script can be vulnerable to corruption:

After that...stay clean!

That's great news!  As far as how I finally cleared the entry . . . I think I missed a step when I used Trend Micro's System Cleaner . . . I think the first time I did not copy the pattern file (lpt$vpn) to the folder with the program file prior to scanning. 

Do you have a recommendation on a routine practice(s) for keeping the system "clean"?  I know the importance of keeping Windows Updates updated and I routinely run Norton AV (incldg live updates), Ad-Aware, Spybot, and Disk Cleaner (not necessarily in that order). Still the Spybot and Sasser worms evidently crept into this notebook.  During this cleaning process (thanks for your help!) I have also used CW Shredder, Hijackthis, Sysclean, Taskill, and McAfee's Stinger Tool.  Should any of these be run routinely?  I love a finely tuned (i.e., clean) system!  Thanks again for your help and for the time you give to help out novices such as myself.
