trojan vundo.eo please help!!

Can anyone help me with this trojan? I have tried several things and and i still cannot get rid of untods.dll. It keeps saying it is being used by another folder. I have tried to find two other dlls that is incorporated by it irl2153ol.dll and q6ps0gTle6.dll, but unsuccessfully cannot find them anywhere.
Does anyone have any info on this subject? Please help!!

Try MoveOnBoot to delete that file.

I tried it and it didn't work. Anymore suggestions? Also
what antivirus program do you believe is the best.
