Mais pourquoi il se déconnecte mon ordi, pas été gentil?

[nenetei]

Salut à tous,

Mon internet se déconnect tous les quarts d'heure, j'ai essayé des antivirus (avast, ewido) des nettoyeurs (regcleaner, cleanup40), des firewalls (kerio) mais rien à faire. J'ai fait un log HiJackThis, voila ce que ça donne:

Est-ce que quelqu'un comprend ce qui se passe, j'ai épuisé toutes mes ressources, et je ne comprends rien au fichier log.

Merci d'avance et bon wikaine

Tous les 1/4 d'heure comme une horloge ? A part Dinst.exe je ne vois rien de traumatisant ! Ca viendrait pas de ton FAI tout simplement ?
