If you are using a good firewall (sygate Por or something) then all I know is to run trojan remover with an updated database.

If you don't have a antitrojan go here for online check

A decent firewall like Agnitum Outpost Firewall will block trojan horses etc., but do a virus-scan to remove those not detected with a firewall.
