Comment eliminer winfixer

Bonjour,
je tente en vain depuis ce matin d'éliminer winfixer qui ouvre des pop-up intempestives sur mon PC . Mais je n'y arrive toujours pas. Alors je fais appelle à vos connaissances.
J'ai suivi les conseils qui se trouvent sur le forum (ad-aware,spybot,a²) et je viens de generer un log hijackthis
