aprés le résulta , j'ai supprimé les fichier infectés.

Salut à toi.
Je pense que la rubrique pare-feux du site :http://www.libellules.ch/dotclear/index.php?category/Firewall---pare-feu
t'apportera les premières réponses pour tes recherches.
Moi j'utilise pctools firewall plus sur un vieux pc tactile de récupération avec win 2000 et cela ne pose aucun souci.
Par contre, et je l'ai lu un peu partout ailleurs que sur ce site que avast posait pas mal de problèmes et qu'il faut lui préférer antivir, que j'utilise sur tout les pc de la maison.
Bailles

Hop, je transfère vers désinfection.
