Impossible de supprimer Trojan.win32.agent.ay

Bonjour,
Me voici bloqué, après plusieurs jours de tentatives d'éradication du trojan "Trojan.win32.agent.ay". J'utilise pour la 1ère fois Hijackthis et je sollicite votre aide pour m'aider à interpréter ce fichier et supprimer les lignes nécessaires pour retrouver un fonctionnement correct de mon PC. Merci par avance de votre précieuse aide (avant formatage de mon disque !!)
