Salut à tous! J'ai récemment été infesté par un virus type cheval de troie (d'après l'antivirus...) mais je n'arrive pas à m'en débarasser! Je m'explique: Le trojan s'est infiltré sur mon ordi, Avast m'en a averti et j'ai supprimé les fichiers par le biais du message d'alerte. Pourtant le fameux " System Defender " est bien présent. J'ai déjà lu plusieurs posts sur le sujet, tenté diverses manœuvres, rien n'y fait... Il se manifeste par : Un raccourci dans la barre de lancement rapide ainsi que sur le bureau et dans la barre des programmes du menu démarrer, et un icône dans la barre en bas à droite à côté de l'horloge. Chacun de ces raccourcis revient au démarrage, même si je les ai supprimé avant d'éteindre mon ordi à l'utilisation précédente. De plus, un message d'erreur s'affiche à chaque démarrage : " Access violation at address 13350EC0 in module 'WSd4aa.exe'. Read of address 00000000.
