Besoin de vous pour supprimer les virus

Bonjour,
Pouvez vous m'aider je ne sais plus comment faire pour supprimer les virus nommé Drive Cleaner et Win Fixer (ils sont détéctés par spyware doctor mais ne les supprime pas)
Mon antivirus est Avast
Mon pare feu : pare feu Windows et Sunbelt Personal Firewall
(le rapport F secure Black Light ne detecte aucun virus et pourtant je sais qu'ils sont encore là...)

Voici le rapport Hijack This :
