merci
en surfan sur le net je croi avoir trouvé ce qui me causai les alertes systeme: blaster
j'ai suivi pas a pas toutes les manipulation indiques sur le site microsoft, j'ai install des mises a jour notamment.
le message ou il y a le compte a rebours n'apparait plus (du moins pour l'instan), cependant quelqu'un peut -il me dire si mon analyse hijackthis presente encore des virus?
