Backdoor.Trojan Problem - Norton cannot remove and Ive tried everything!

I have Symantec antivirus running, and have a permanent window popped up which I cant close, saying:

--------------------------------
Norton Antivirus has detected a virus on your computer
C:\WINDOWS\Syetem32\combmjk.dll
Backdoor.Trojan
----------------------------------------

Here are results from other things I have done (both in normal and safe mode):

Run Norton in safe mode, it still cannot remove the infected file
Searched for combmjk.dll, this file doesnt exist
Searched the registry for this file - there is reference to it  in Search Assistant - My search
Could not uninstall My search thgough Add/remove programs (Specified module could not be found)
Could not find the path to where Add/remove progrmas thought this was installed so cant delete manually
Cleared all temp files, and IE cache etc

CW-shredder runs clear
Spybot S&D just brings up the old DSO exploit thats always returns when deleted
Spy Sweeper runs clear
Pest Patrol runs clear

I have set the points on this quite high so hopefully we can go backwards and forwards fairly quickly to get this solved if possible!

Thanks
