Explorer se ferme tout seul, pop-up frequent

A l'aide, je sais plus quoi faire.

mon explorer windows(vista) se ferme automatiquement quand j'ouvre le poste de travail ou parfois quand je navigue avec IE. plusieur pop-up ouvre également sois des nouvelle fenetre ou 40-50 nouvel onglets. J'ai aussi aux 2 minutes des erreurs de dll manquant suite a vundofix. Voici le hijackthis.
Merci de m'aider.
