Interprétation d'un rapport HijackThis

Bonjour tout le monde, depuis quelques jours j'ai des petits soucis lorsque je démarre Internet.
Ma page est dirigée vers www.searchqu.com/406 et je n'arrive pas à la modifier même en allant dans outils => options => general => page d'accueil : www.google.fr/firefox. Bref ça revient toujours!

J'ai donc fais des recherches sur Internet et j'ai trouvé ça : http://www.commentcamarche.net/faq/991-une-solution-pour-about-blank

C'est un site très interessant, mais ne m'y connaissant pas vraiment en virus, cheval de troie et informatique en général je me retrouve bloqué à la seconde étape qui est de supprimer les lignes payantes sur le logiciel HijackThis!

Je vous envoie donc mon log en éspérant que vous me disiez les lignes que je dois supprimer:
