Infection pc

Bonjour,
Je suis sous WIN XP SP3
Depuis un certain temps mon pc au demarrage m'affiche des messages d'erreur type c:win\syst32\KOZEZUPO.dll ou RIBEMAGO.dll et d'autres...
J'ai fais des analyses antivirus, plusieurs logiciels anti spyware trojan, comme spybot ad-aware, spyrware pc doctor.
Et rien ne change. Si quelqu'un pouvait me venir en aide!!!!!!!!
Voici un rapport Hijackthis:
