Netsky.C est un virus qui se propage par email
et via les dossiers partagés. Il se présente sous
la forme d'un message dont le titre et le corps sont aléatoires,
avec un fichier joint (25 Ko) dont l'extension est .COM, .EXE,
.PIF, .SCR ou .ZIP. Si ce dernier est exécuté,
le virus s'envoie aux adresses présentes dans le carnet
d'adresses Windows ainsi que divers autres fichiers du disque
dur, puis tente le cas échéant de se propager
via KaZaA et les dossiers mis en partage en s'y copiant sous
divers noms aguicheurs.
PREVENTION :
Les utilisateurs concernés doivent mettre
à jour leur antivirus. D'une manière générale,
même si son nom est attrayant il ne faut pas exécuter
un fichier joint sans l'avoir au préalable analysé avec
un antivirus à jour.
DESINFECTION :
Avant de commencer la désinfection, il est impératif
de s'assurer avoir appliqué les mesures préventives
ci-dessus afin d'empêcher toute réinfection
de l'ordinateur par le virus. Les utilisateurs ne disposant
pas d'un antivirus peuvent utiliser gratuitement l'utilitaire
de désinfection FxNetsky pour rechercher
et éliminer le virus.

Windows ainsi que les fichiers .ADB, .ASP, .CGI, .DBX, .DHTM,
.DOC, .EML, .HTM, .HTML, .MSG, .OFT, .PHP, .PL, .RFT, .SHT,
