Infection win32

Bonjour,

J'ai allumé adsl tv hier et mon pc s'est éteint. Depuis avast et spybot me trouve une infection win32 (j'ai pas eu le temps de retenir lequel?) et je pensais avoir supprimé l'infection mais aujourd'hui tout est revenu et mon pc bug.

Ci dessous le log hijackthis et malware si quelqu'un peut m'aider à déchiffrer? Merci d'avance...
