[trojan horse collected.6.BN] et log HijackTh

Bonsoir, je suis là pour aider un ami, qui apparament est infecté par trojan horse collected.6.BN! Connaissant un peu les differents programmes qui permettent de desinfecter les PC, je lui ai conseillé AVG pour le trojant, des scan sur le net etc.. et AVG detecte avfax.dll comme trojant.. J'imagine qu'il ne sagit pas du virus, mais d'une dll infectée. Je lui ai donc conseillé de ne pas la supprimer et de faire un log HijackTh. C'est là que vous intervenez ;p! je ne comprend rien aux logs d'HijackTh et je sais encore moin réparer les erreurs. Si vous pouviez m'aider (l'aider), se serait vraiment l'ideal!
Je ne peux malheureusement pas vous donner le configuration de mon ami, je n'ai pas regardé (honte à moi). Juste qu'il est sous winXP.

Voici le log :

Donc j'imagine que le trojant est quelque part la dedans.
J'ai aussi remarqué les lignes O1 - Hosts: xxx.com ("x" etant indéfini dans cet exemple). Daprès le site d'HijackTh, ces lignes sont à effacer.

Voila, si vous pouviez m'aider (aider mon ami surtout) à faire en sorte qu'il ai à nouveau un PC clean, je vous en serai tres reconnaissant, ainsi que lui.

Si je n'ai pas ete assez clair, pas assez explicite, ou qu'il vous manque des details, n'hesitez pas à me le dire, je me ferais une joi d'y remedier.

Merci d'avance,
cordialement,
Gabb
