Bonjour,
j'ai depuis quelques jours un cheval de troie nommé win32:vundo@dll.Quand avast me previent avec une alerte et me demande de le supprimer, je le supprime et ca marche mais au bout d'un petit moment une autre alerte surgit en me disant que le programme a detecté ce cheval de troie.Voila j'espere que quelqu'un pourra m'aider a régler ce probleme, merci d'avance.
