Mon PC est infecté. Help ! Merci d'avance !!!

Bonjour à tous,

Voici mon souci : je me retrouve avec une petite icone triangulaire jaune à côté de mon horloge qui m'indique sans arrêt que mon PC est infecté, j'ai des icones qui sont apparues sur mon bureau dont je n'arrive pas à me débarasser (online security guide et live safety center), j'ai des fenêtres Internet Explorer qui s'ouvrent sans que je demande quoi que ce soit (qui pointent sur savetheinformation.com, www.protectroom.com) , mon PC rame, ...etc.

J'ai un peu regardé sur le site et j'ai scrupuleusement appliqué la méthode préliminaire de désinfection (CCCleaner, puis AVG anti-spyware, puis BitDefender, et enfin Hijackthis). Les symptomes n'ont malheureusement pas disparu. Il me reste donc plus qu'à m'adresser à un expert ! Merci par avance pour votre aide !!!
