Google fait des siennes... Rapport HijackThis

Bonjour à tous,

Je débute sur le forum alors j'espère que je suis au bon endroit...

Lorsque je fais une recherche sur Google, près d'une page de résultat sur deux me dirige vers un site qui n'a rien à voir avec ma requête: casino, jeux en ligne, moteurs de recherche inefficace... De quoi devenir dingue!

J'ai essayé de résoudre le problème par plusieurs moyens: spybot, ad-aware, CW shredder, F-Secure... sans succès! Mon malheur persiste! :-)

Voilà pourquoi je me permets de poster ci-dessous un rapport obtenu avec HijackThis, logiciel réputé dont je ne maîtrise pas toutes les subtilités...
Merci d'avance à tous ceux qui prendront de leur temps pour y jeter un coup d'oeil.
