My System is attacked by trojan Horse!!!!

Since you were already infected with a virus, I suggest that you try to download a free tiral of Kaspersky and Symantec antivirus. Both these two are very effective when it comes on scanning and detecting viruses, malwares, and worms. After downloading this software, make a full scan in safe mode. Please quarantine whatever it finds and delete it. If still no success, since you do not want to reformat your machine, I suggest that you visit www.bleepingcomputer.com There you can contact one of the HJT expert there to help solve your problem and for assistance. I am pretty sure they would really help you. Just follow their instructions carefully so that you will be guided accordingly. Hope this would help to you in any way! Have a great day and God speed!
