I have two pc's with dll's I can't seem to get rid of. Can anyone help me?

Here are three of them:

KHFDCDC.DLL
AWTUSRR.DLL
JKKJI.DLL

Hi are you deleting them because of a virus?

There trojans and should be visible via a Hijack this log in the system 32 folder, do the prwork in my sig and post results, one of the techies will have a look. it should be fairly easy to remove using Ewido run in safe mode, do the prework first though.
