[XP] Pc TRES lent

Bonjour à tous!

J'ai un problème avec mon PC portable qui rame énormément et ça du jour au lendemain!!
J'ai effectué un scan de mon pc avec Virus scan Pro, Ad-aware, Spybot et Ccleaner mais rien n'a été trouvé...
après lecture de quelques posts sur le forum du site, j'ai fait un scan avec Hijackthis,voci le log obtenu :
