Bonjour tout le monde.
C'est aussi noel pour les virus, et ils se sont fait plaisir chez moi...

Je dois cliquer 5 ou 6 fois sur mon icone internet explorer pour y accéder...ca me met internet explorer a rencontré un probleme et doit fermer.
Quand j'arrive à y accéder, un message me demande de dl un anti malware(que je n'ai pas fais) ou bien des pages non solicitées s'ouvrent toutes seules (Nester).

J'ai aussi une connexion trés lente depuis ces phénomenes.
Il n'y a pas que la connexion d'ailleur mais tout le systeme!
