Exlorer.exe disparait après 8 secondes (Vista

Bonjour,
Sous Vista quand j'ouvre une fenêtre avec explorer.exe, (donc pour tous les dossiers), celle ci disparait après 8 secondes environ.
Parfois ce sont les icônes du bureau et la barre de taches qui disparaissent, il faut passer par le gestionnaire de taches et relancer explorer.exe et ça revient.
En mode sans échec ça tient et sous freecommander aussi.

Qu'a donc mon explorer je n'ai pas envie de formater.
J'ai passer tous les antivirus en ligne que j'ai pu les antispywares aussi, il ne me reste qu'a vous soumettre mon hijackthis.log
