How can I delete Infostealer.Gampass Virus

[gailio]

My computer has been infected with 3 Infostealer.Gampass viruses. I have tried several things to get rid of these and still it remains. No matter what I try I cannot find where it is located on my computer. I am running on Windows XP, use Norton as my VP and I am a complete beginner when it comes to sorting out viruses.

Any help would be greatly appreciated.
