Problème de virus, besoin d'aide svp

Bonjour,
Cette nuit, j'ai eu une grosse attaque de virus, avec des programmes qui se sont installé tout seuls sur mon ordi.
J'ai fait pas mal de ménage (2fois MBAM, 1scan avec antivir, 1fois spybot), mais j'aimerais être sur qu'il ne reste rien sur mon ordi.
Je vous met le rapport Hijackthis que je viens de faire
Merci de votre aide
