Pubs intempestives - Spyware-Secure, etc.

Bonjour,

Depuis deux-trois semaines, je suis victime de pubs intempestives dans IE7. J'ai bien lu quelques posts dans ce forum mais les outils qui étaient proposés n'étaient soit plus disponibles, soit inappropriés pour Windows Vista. Quelqu'un aurait-il l'amabilité de m'aider? Voici le log Hijack:
