Ordinateur de + en + lent (et rapport hijack)

Bonjour,

Voila, j'ai un ACER TravelMate 8210
(Centrino Duo 7200, 2Go, ATI X1600, XP Pro)
au démarrage il utilise 700Mo de mémoire et il est devenu vraiment lent, c'est assez chiant, il n'a même pas 6 mois...
j'ai AVG 7.5 Internet Security, je fais régulirèrement Spyboot, CCLeaner... mais il doit y avoir des processus inutile qui me bouffe trop de mémoire...
J'ai lancé un hijackthis ce matin, voila le résultat:
