I have Trojan "Infostealer.gampass" and can't remove

I have had this Trojan for a while now i think, because it just started to slow down my computer.

I recently scanned my computer with, Norton Virus 07, HouseCall online virus scan, and i will try everything else people are going to recommend me to use.

I started noticing this when my computer all of a sudden got slow,
i thought it was some programs i downloaded, so i deleted them, still didn't help, so i recently scanned Norton Virus and i freaked out cause i couldn't get the Trojan off my computer.

Now I'm pretty desperate and i think this website would really help me find a solution.

Please help, thanks.
