PC très lent

Bsr, svp j'ai un Compaq presario c700 avec 3Go de ram et tout marchait bien, jusqu'ç dernièrement où j'ai remarqué que mon pc est de plus en plus lent. La souris se déplace lentement mon processeur est tjr a 100% et la ram est occupée a 2go voir plus avec seulement Firefox et MSN lancé. J'ai Kaspersky 2010 et j'ai déja lancé l scan mais rien, et j'ai installé cccleaner mais il n'y a aucun changement. Svp aidez moi j'ai pas envi de formater et quel antivirus me conseillez vous parce que Kaspersky j'ai pas aimé.

Sinn voila le rapport HIjackthis si ça peut aider.
