PC has IRC bot

[Fulcrum]

Apparently my computer has an Irc.bot, and my ISP has suspended my account with them for a week now because the virus was affecting their network, I ran 8 different anti-virus, anti-spyware, anti-malware, anti-everything programs, and they all show as clean, now i understand that the virus can still be hidden --
is there anything i can do to avoid reformating my computer ? They say if i activate it and they see that the virus is still there, they suspended me for a month

Running Windows Xp Pro
not getting any error messages, although my computer has been taking a REALLLLY long time to shut down ... never did this before...

Thank for your time
