What firewall are you using to prevent any outgoing traffic from your "trojan"? Have you disabled "system restore" and restarted your computer? Have you emptied the temp internet files and off line content? If not, do these tasks and then go to http://www.pcflank.com/ and use their trojan scans. If PC Flank's scans detect a trojan, you can select one from PC Flank that is highly rate and download a free trial version to clean/delete/repair the trojan from their website. There are several programs that are effective and easy to use(Trojan Remover, Trojan Hunter, TDS, Tauscan to name a few).
