Problème Virus : processus *.EXE créés

Bonjour à tous,

Depuis avant-hier, j'ai attrapé un virus que je n'arrive pas à supprimer malgré les informations recueillies sur divers forums.

Il crée des fichiers dans C:\windows\temp\*.exe et c:\windows\system32\*.dll


Voici l'état de mon log HiJack This :
