Pc tres lent

Bonjour,

Depuis plusieurs jours maintenant, mon pc est devenu très lent, au point qu'il est presque devenu inutilisable (internet met plusieurs minutes à s'ouvrir, de long bugs d'affichages, temps de démarrage excessif....). J'ai déjà fait une recherche de virus, rien trouvé à ce niveau là ; j'ai lancer ccleaner plusieurs fois mais toujours le même problème.

Je commence à être à cour d'idée, je me tourne donc vers vous. J'ai vraiment besoin d'un coups de main.

Je vous join le rapport hijackthis, en espérant que vous pourrez m'aider... Ciao !
