Probléme de lenteur sur PC

Bonjour,
rencontre depuis qqes temps une lenteur extreme à l'usage de mon pc. J'ai téléchargé hijackthis et vous propose la log éditée à l'analyse.

Je ne suis pas trés calé dans cette liste d'applications mais j'en déduis qu'il y a un certain nombre d'applications inutiles qui caramélise les performances.

Merci pour vos conseils éclairés
