I'm afraid the best thing to do is to back up your data to another disk, then format the whole harddrive and reinstall the windows again. Before you load the data back to your hard drive, use anti-virus/spyware software to scan your backup disk first in case trojan is still somewhere in the disk.

These steps sound tedious but it will save your headache later on.
