Begin your own thread. This one is two years old and you won't receive help within somebody else's thread. We need full information, operating system, anti-virus program, firewall and how do you know you are infected.
Follow the steps given here and then begin your own thread with all requested information and required logs and you will receive help, until you do that you cannot be offered assistance.
