Navigation internet très lente

Bonjour,

voici mon problème:

Je suis sous firefox et ma navigation est très lente! Pourtant ma connexion fonctionnent très bien et lors de téléchargements, mes débits de download sont très bon.

Donc j'aimerais savoir d'où peut venir le problème.

J'ai pensé à un virus mais avast me dit que tout est en ordre (bon voilà c'est avast je sais... mais normalement il fonctionne pas trop mal)

Donc j'ai pensé à un truc plus vicieux genre un spyware ou autre "saloperie" mais spybot me dit la même chose.

Donc j'en viens à vous demander votre aide:

voici ce que me renvoie hijack...:
