Infecté par Win32:Spyware-gen, besoin d'aide

Bonjour à tous,
je suis infecté depuis maintenant 3 jours par le troyan Win32:Spyware-gen, détecté par Avast. Le fichier contaminé est svchost.exe, d'où l'impossibilité de le supprimer ou de le mettre en quarantaine.

Je vous remercie d'avance pour votre aide.

Antonius
