Recently I noticed XP running slower than usual where exlorer.exe process was choking most of the processor time.I then investigated the system processes which showed up RunDLL32.exe P06620Pin.dll and RunDll32EP all in the one process stream.Are these causing the problem? The system has been scanned with AVG Antivirus,Ad-Ware SE and SpyBot S&D malware removers but nothing has been identified.

Any pointers would be much appreicated and the XP system HijackThis log is here.
