Well as u all know i reformatted my computer and followed all of ur steps to remove that Backdoor.Trojan now other virus's are popping out of no where and i keep deleting them but new ones come up.  I just put the latest updates for Norton and everything even a firewall beofre i did anything, Isass.exe also came up but i was able to delete it through the registry.  Does anyone know any other stronger anti-virus software other than Norton because i think it is getting me no where...  It will be a great help once again, thanks a bunch.
