Ok, I still need help

Thanks for all the assistance so far, I'm very appreciative. I've followed the tutorial Read and Run Me First and followed it as best I could. During several of the scans my PC apparently shut down, particularly during counterspy and the online scans, leaving no log files I could find.
I also ran AVG anti-spyware due to this problem and it did in fact find a trojan which is currently in quarrantine.

I DO KNOW that the malware I'm having the problem with was downloaded 4/12/2007 @ 8:39am specifically. I've gone through several hundred files searching their "created date and time" and have rid myself of all which occurred then that I could find with the exception of c:/Documents and Settings/Network Service/Local settings/application data/Microsoft/Windows/UsrClassDatFile 256KB which I am unable to access or delete as it's associated program is always running, which I haven't found.

When I shut down or restart I get the following message;
Exception 0x0eefade occurred at location 0x7c812a5b

I'm not sure the location is always the same but the message is similar and the exception number is always the same.

This damn thing is running an icon in my system tray that takes me to the spylocked.com website and responds in no other way regardless of whether it is left or right clicked etc.

I have attached logs from getrunkey and shownew as well as hijack this, hope you can find what i'm not understanding, ... I "see" but don't know

If you need it I can also post the log from AVG antispy.
