Virus persistant : rapport hijackthis

Bonjour,
j'ai un probleme, mon fond d'ecran est tout blanc, ce message apparait lors du lancement de la session:

'file:///C:/WINDOWS/privacy_danger/index.htm' est introuvable.
Vérifier que le chemin d'accès ou l'adresse internet sont corrects

De plus j'ai déja éliminer des trojans vundo avec malwarebytes et virtumonde avec spybot.

Voici mon rapport Hijachthis:
