Connexion trop lente

Bonjour,
ma connexion internet est inégale, il arrive que cela soit compliqué ne serait-ce que d'atteindre un site, ouvrir une page web prend un temps considérable parfois (souvent).
J'ai passé spybot, anti-malware et avira en mode sans echec mais rien n'y fait...je ne peux meme pas me connecter sur msn parfois..je vous donne le rapport hijack et je si quelqu'un a une idée...
