Trojan-Downloader.Win32.Agent variant

bonjour,

applique ceci et tiens nous au courant
Méthode préliminaire de désinfection - Version Fr

cordialement

a lire:
page internet google redirigee
(cas n° 2)
et:
virus methode preliminaire de desinfection version fr
et aussi de la bonne lecture:
securite proteger un ordinateur contre les malwares d internet

Alors voila, j'ai lu la méthode préliminaire de désinfection et je l'ai appliquée mais je rencontre plusieurs soucis :

CCleaner tout se passe bien, il me supprime pas mal d'erreurs etc mais tjs le virus détecté par Wow

AVG anti spyware, je le lances, je télécharges les mises à jours et je lance une analyse complete du systeme mais a peu pres a la moitié, j'ai un message d'erreur qui coupe aussitot le logiciel.
J'ai donc essayer les autres analyses moins completes, et la il n'y a aucun probleme. Je les ai donc faites toutes mais je ne sais pas si cela remplace une analyse complete.Voici le message d'erreur :

AVG Anti-Spyware 7.5 Exception
Something bad happened in the application. Error diagnostic file saved to C:\Program Files\Grisoft\AVG Anti-Spyware 7.5\avgas.err

J'en ai relancé plein des analyses completes en redémarrant le pc mais pas moyen d'arriver au bout.

Ensuite avec BitDefender, je lance le scan en ligne, j'accepte l'activeX mais des que le scan démarre, il se coupe en meme tps que la fenetre d'IE. Le scan n'est donc pas effectué.

Concernant les pages internet redirigées, j'ai pu constater ce probleme avec IE que je viens d'installer (je n'avais que FireFox). FireFox fonctionne bien.
Je télécharge fixwareout, je l'installe, je clique sur finish donc ensuite mon pc redémarre.

Voici le rapport de FixWareOut :
