This is a network computer at work.
I have tried several means of deleting this file such as:
File Assassin in normal & safe mode
Hijackthis
AVG Antivirus 7.5 can put it in the vault but it keeps coming back. AVG calls it "Trojan horse Downloader.Delf.12.AN"
AVG Antispyware
Also have a combofix log.

Hijackthis log:

End of file - 1702 bytes

Also did online Kaspersky scan (I have a report) it picked up

C:\Documents and Settings\tracey\Desktop\Unused Desktop Shortcuts\one_ring.exe/WISE0016.BIN Infected: Backdoor.Win32.Ruledor.c skipped
C:\Documents and Settings\tracey\Desktop\Unused Desktop Shortcuts\one_ring.exe WiseSFX: infected - 1 skipped
C:\Documents and Settings\tracey\My Documents\miscelanious\one_ring.exe/WISE0016.BIN Infected: Backdoor.Win32.Ruledor.c skipped
C:\Documents and Settings\tracey\My Documents\miscelanious\one_ring.exe WiseSFX: infected - 1 skipped

Don't know if these infections above are connected with bthc.dll or not.

"C:\WINDOWS\SYSTEM32\bthc.1 Infected: Trojan.Win32.Pakes.cdw" I managed to delete this file,

but it didn't pick up

C:\WINDOWS\SYSTEM32\bthc.dll Object is locked skipped

Only thing that is happening on this computer avg keeps popping up & I just click ignore because I know avg can't fix it.

Thanks in advance

Resolved: I fixed it by using sdfix.
I read another post & someone suggested to use it for another problem.

Thanks anyway
