Problème de google qui perd la tête

Bonjour,
Depuis une visite hasardeuse sur un site de P2P, mes recherches internet ont perdus la tete ! Lenteur extrême de la connexion, liens qui renvoient vers des sites fantaisistes, sites qui ne s'affichent pas, téléchargmeents qui ne fonctionnent pas... Et ce, avec Mozilla 3.0 ou IE 7
Je ne suis actuellement pas sur mon ordinateur,mais j'ai réalisé hier un Hijackthis que je vous soumets ci dessous...
Merci pour votre aide, je suis complètement perdu (des passages d'Avast Antivirus, Spybot et Adaware n'ont rien changé !).
