Aide, infesté par Win32:Adware-gen

Bonjour,
J'ai le virus win32:adware-gen et je suis incapable de m'en débarasser. Je n'ai plus accès au panneau de configuration ni au lecteur c:. On me dit que je n'ai pas les droits administrateurs. Cest avast qui détecte ce virus et quand je le supprime il revient toujours. Le nom du fichier est C:\WINDOWS\system32\pphcj9nj0e96c.exe
Il y a le logiciel "Antivirus XP 2008" qui s'est installé tout seul et "Spyware & Malware protection" aussi. Après avoir lu sur plusieurs forum la démarche à suivre, mon pc fonctionne toujours aussi mal et est toujours infecté. Je soumets donc un log provenant de HiJackThis. En espérant que quelqu'un puisse m'aider.
Merci!
