Analyse Hijackthis

Bonjour,
Mon ordinateur est devenu très lent (video streaming hachées, problèmes avec divers softs de créations audio et video) et aucun moyen de savoir d'où ça vient. Ou plutot ce que je sais, c'est quà l'utilisation d'un soft, la charge CPU est très vite énorme. C'est très pénalisant pour moi. J'ai fait une analyse antivirus, sans resultat, une autre Hijackthis, que je vous fait parvenir, merci à ceux qui y prêteront attention...
