2 trojans sur mon pc: n'arrive pas à éliminer

Bonjourà tous,
je galère depuis 15 jours avec une invasion que j ai attrapé betement par msn en ouvrant un fichier image.
J ai nettoyé avec avast puis antivir, puis j ai nettoyé avec MSN fix. Tout cela a pas mal fonctionner mais il me reste 2 trojans que je n'arrive pas à éliminer: (detection antivir toutes les 2 secondes)
- c:\windows\system32\pmnon.dll : Vundo.gen
- c:\windows\system32\xxyyvsp.dll : agent 38912

Depuis j'ai utilisé vundofix, fixvundo et hijackthis comme il est proposé sur d'autres discussions du forum mais rien n'y fait.
Ci après, je poste les Rapports vundofix, fixvundo et hijackthis.

Je suis plutôt limité en informatique. J' en appelle donc à vos connaissances en la matière pour me donner ce coup de main si possible.
Merci et à très vite j'espère.
