Pc de plus en plus lent

Bonjour,
De temps en temps mon Pc rame beaucoup et je dois redemarrer pour arranger ça, mais parfois ça s"améliore 5mn

Normalement je n'ai pas de virus (AVG mis a jour très regulierement + scan occasionnel avec Bit defender Free)
et aussi scan regulier avec Spybot ...

voici le log de HijackThis

Merci de votre aide ....
