Infestée par spywares

Bonjour à tous,

Malgré l'utilisation de CCleaner, Clean, Clean Up, Spybot, Ad Aware, AVG Antispyware a trouvé un certain nombre de fichiers infectés...
Dans l'immédiat, j'ai mis ces fichiers en quarantaine mais je souhaiterais les supprimer définitivement de mon système sans commettre une erreur.
