Livebox ralentie depuis passage sous seven

Bonjour,
Je me permet de demander de l'aide sur commentçamarche suite à un problème récurrent avec ma connexion internet.
Possédant un abonnement chez orange, j'avais 2 machines (un pc sous XP et un mac sous léopard) utilisant cette connexion sans trop de problèmes, puis j'ai acheter un nouveau pc tournant sous Seven.
Très vite la connexion c'est détériorée pour toutes les machines pour atteindre un niveau ridicule (environ 25ko/s en descendant selon le test de journaldunet.com). Cependant si je déconnecte le pc sous Seven, les autres machines retrouve une connexion normale.
Ce pc étant devenu ma principale station de travail je me retrouve complétement bloqué depuis plus d'un mois, après avoir essayé divers anti-virus et firewalls, je n'est toujours pas résolu mon problème.
Je me tourne alors vers vous pour des idées ou des avis sur mon problème, je joins un rapport hijackthis au cas où même si celui-ci ma l'air relativement propre.
