5 win32 différents...

Bonjour,
J'ai récupérer le Pc d'un collègue qui a chopé des p'tit trojans sympathiques.

J'ai scanné avec avast et voici la liste:
win32:obfuscated-BPP
win32:Agent-ROU
win32:Agent-JNY
win32:spywaresecure
win32:Adware-GEN

J'ai scanné avec AVG et lui n'a rien trouvé, a part des tracking cookies (que j'ai viré au passage...)

J'ai passé hijackthis et voici le log:

C'est bizarre mais il ne semble pas donner grand chose. Je suis loin d'être expert dans la lecture de log donc, je vous laisse juges...
Je précise que j'ai passé hijackthis en premier.

Sa config: win vista famillial premium, internet explorer, antivirus avast! (mais vous l'aurez déjà remarqué...) et pas de firewall ni d'antispyware (vous l'aviez surement déjà compris).

Voili.
Je suis pas un expert de la désinfection et encore moins de Vista.
Donc j'accepterai avec reconnaissance un ch'ti coup d'main.
Merci beaucoup.
