Ralentissement de l'ordinateur

Bonjour tout le monde

c'est mon premier post sur ce site, je vais pouvoir tester sa fonctionnalité.

Je vous expose mon probleme en ésperant que des ames charitables m'aide a le résoudre.

voila je possede windows XP sp2 ainsi que antivir zone alarm et ad-ware. depuis un certain temps mon ordinateur ralenti et quand je vais voir le gestionnaire des taches je ne suis jamais a 1% je tourne entre 2 et 20 de l'utilisation de l'uc. j'ai fait un scan antivirus . un scan pour les adwares mais je n'ai rien trouvé. voyant ces echecs. je ne comprend pas qu'est-ce qui affecte ce ralentissement. j'ai utilisé ccleaner pour nettoyer tout . un chkdsk /f installé toutes les mises a jour en date mais rien n'y fait. je poste un rapport hijackthis qui je pense pourra éclaircir certains d'entre vous
