Besoin d'un coup de main

Bonjour a tous! je souffre actuellement de soucis avec ma page de démarrage qui ne cesse de changer et de problemes de redirections vers des pages erronées.En parcourant votre forum, j'ai compris que j'avais été infecté par un spyware, et j'ai téléchargé hijack this, en esperant qu'une ame charitable veuille bien interpreter mon log! d'avance merci.
