"Firefox m'a tuer"

Bonjour,

Semblerait que Firefox dernière mouture (3.6.4) ait été le vecteur d'infection pour une cochonnerie dont je n'arrive pas à me débarrasser.

Symptomes: instabilité progressive vers BSOD, recherches qui basculent sur Ask.com, volet d'exploration de l'Explorateur Windows remplacé par "Ask Toolbar Quick View"...

Voici un log HijackThis frais, toute aide serait précieuse, merci!
