[Hijacking] Problèmes de spyware ou de hijack

Salut a tous,

voila mon soucis: il ya quelques jours, mon pc c allumé avec un écran noir et un warning en fond d'écran. Je n'arrive pas a l'enlever malgré tous mes essais. Je dois dire que je ne suis pas super doué en sécurité. J'ai essayé de regarder dans la base de registre et d'enlever les processus suspsect. j'ai utilisé Spybot, xsoft,spysweeper mais rien. Ils m(ont trouvé des cookies ou des trojans mais rien qui ne m'aide sur mon probléme de fond d'écran et à premiére vue de hijacking.

Voici monHijack:
