PC infecté par Hacktool, Trojan Horse et Trojan.Cmapp

Salut à tous,
Mon Pc est (pour la 1ere fois je pense) infecté.
Norton a identifié 3 problèmes suivants :
1) Hacktool : virus, objet c:\windows\blvaisj.exe
2) Trojan Horse c:\windows\evpgbsb.exe
3) Trojan.Cmapp c:\programfiles\cmsystem\Cmsystem.exe

Le PC fonctionne, certes lentement et la fenetre rouge d'alerte Virus et toujours active.

Je me suis inscrit et j'ai effectué la 1ere preconisation dans les différents forum (l'execution de HiJackThis qui renvoie ce fichier texte)

Merci de m'aider

Esteban
J'ai effectué une analyse Norton en mode sans echec comme précisé.
A la fin du scan, deux virus ont été "réparés" puis j'ai mis en quarantaine le dernier restant (Trojan Horse).

Je n'ai plus pour l'instant d'alerte Virus.

Merci à toi Esteban.
