Salut.
Dans le gestionnaire de tache termine:
irdvxc.exe et urdvxc.exe (tu devra peut-être le faire en mode sans echec)
Puis fixe les lignes:
O23 - Service: Network helper Service (MSDisk) - Unknown owner - C:\WINDOWS\System32\irdvxc.exe" /service (file missing)
O23 - Service: Network Windows Service (MSWindows) - Unknown owner - C:\WINDOWS\System32\urdvxc.exe" /service (file missing)
Efface les fichiers en question.
Telecharge CCleaner et nettoie la base de registre.
Reboot et relance un HijackThis.
