Ordinateur qui rame et se bloque souvent

Bonsoir,

J'ai un souci avec mon ordinateur qui rame comme jamais. Plusieurs fois par jour "(ne répond pas)" apparaît en haut à côté du nom du programme. Je suis à chaque fois obligée d'ouvrir le gestionnaire de tâches. Je pense avoir une vilaine cochonnerie sur mon ordinateur. Mon anti-virus Antivir ne détecte rien, mes anti-spywares non plus (AVG et Spyware Doctor), j'ai même fait un scan avec AVG anti-rootkit qui n'a rien détecté non plus.
Voici un rapport hijack this, si quelqu'un peut m'aider, merci beaucoup.
