Svp de l'aide voilà le log hijackthis

Bonsoir
Svp depuis quelques temps mon ordinateur portable rame et surtout se plante assez souvent. Je sais il a une petite mémoire vive mais il n'était pas comme ça. J'ai remarqué que par exemple kavsvc.exe bouffe plus de mémoire que d'habitude.
Voilà je vous donne le log hijackthis et je compte sur vous pour rémédier à certains problèmes.
Sachant que ma page de démarrage est google et que je n'ai pas des jeux installés sur mon ordinateur.
J'ai remarqué que lorsque Kaspersky est arrêté toute application (yahoo messenger, firefox...)s'ouvre plus rapidement que lorsque kaspersky fonctionne
Merci d'avance
