Need help getting rid of Infostealer gampass trojan

[chipmunkalvin]

Specs:
Alienware Aurora 7500-R4
AMD athlon
OS Name Microsoft Windows XP Professional
Version 5.1.2600 Service Pack 2 Build 2600
System Type X86-based PC
Processor x86 Family 15 Model 75 Stepping 2 AuthenticAMD ~2410 Mhz

Problem:
I've had a continuous pop-up from Norton that my comp has a trojan: Infostealer gampass. When I clean/delete/exterminate these viruses, they seem to disappear; only to have Norton tell me they're still there next time I log on to my comp.

I followed the guidelines per Symantec's removal rules but after a full system scan, it still states I have the same trojan on my comp.

I've followed the preliminary removal instructions and have attached the logs. Help please!

Many thanks in advance.

It just freezes on me every time I've tried to run this. I thought Secunia was pretty legit, what happened?

Cheers!
