Ouverture des pages internet trop lente

Bonjour,
Je voulais votre aide s'il vous plait, Moi aussi les ouvertures de mes pages internet sont trop longues. Meme sur les sites comme dailymotion ou autres le chargement des vidéo est vrément long.

J'utlise Firefox et Internet Explorer cela ne change pas grand chose

Je ne telecharge pas

Je suis connecté en cable Adsl et en WIFI , en Wifi c'est encore bien plus long

J'ai Avast comme antivirus

et J'ai windows Wista

Si Quelqu'un pourrai me dire comment faire pour avoir une connexion bien plus rapide je le remercie d'avance.

Voici le scan que j'ai pu faire avec HijackThis :
