Depuis quelques jours je trouve que mon PC est lent, par exemple, google chrome est plus long à s'ouvrir, j'ai des saccades dans le moindre jeu alors qu'avant tout fonctionnait normalement.
Il y a surement pas mal de ménage à faire dans mon PC, j'ai déjà effectué des analyses (CCleaner, MBAM, Combofix) quelques erreurs et virus ont été supprimés.
Parfois l'utilisation de mon processeur augmente sans aucune raison.
Je post mon log Hijackthis, ça serait sympa si quelqu'un pouvait m'aider

Merci
