Problème pour supprimer Trojan

Salut à tous

Mon anti-virus a détécté la présence de trojans. Depuis, je n'arrive plus à démarrer en mode normal. J'ai chercher en vain à les supprimer, mais mon anti-virus n'arrive pas à les supprimer. J'ai aussi lancé adware et un anti-spyware, rien à faire. Je vous laisse un log hijackthis. Merci pour votre aide
