Problème apparition / disparition Explorer.ex

Bonjour,

Depuis quelques jours, j'ai l'explorer qui saute puis qui revient et ainsi de suite ...

J'ai fait moultes analyses ( Ad-aware, AVGAS, Norton 360, SpybotSD, BitDefender On-line) et j'ai trouvé virtumonde.dll ( vundo pour les intimes) que j'ai enlevé. J'ai même pris VundoFix ensuite pour être sûr de l'avoir enlevé: les 2 versions que j'ai prises ne l'ont plus détecté.

Voici le log Hijackthis:
