Virus DA UMA ... MSN

Salut

Ton pc est bien infecté, entre autre par le ver alcan.
On va donc commencer par le plus urgent:

Télécharge BruteForce Uninstaller ici:
http://www.merijn.org/files/bfu.zip
Créé un nouveau dossier sur le bureau et, dezippe le fichier telechargé à l'interieur

Ensuite, fais un clic droit sur ce lien : http://metallica.geekstogo.com/alcanshorty.bfu
et clic sur "enregistrer la cible sous".
Enregistre ce fichier dans le nouveau dossier que tu as crée sur le bureau
Tu aura donc les deux fichiers BFU.exe et alcanshorty.bfu à l'interieur de ce dossier.

Lance "BruteForce Uninstaller" en cliquant sur BFU.exe
Clic sur le petit dossier jaune, et clique sur : alcanshorty.bfu
Coches la case "Show log" after script ends
Clique sur Execute pour lancer les opérations.

Attends que le message Complete script execution apparaîsse et clique sur OK.
Un rapport va s'afficher dans la fenetre du programme, copie et colle ici à la suite de ton message, ainsi qu'un nouveau rapport hijackthis.
Clique Exit pour fermer le programme BFU.

Ensuite on s'occupera du ver MSN.

Bonsoir Galou01

Avant de continuer, est ce que tu peux aller sur ce site:
http://www.virustotal.com/xhtml/virustotal_en.html
et faire analyser ces deux fichiers en ligne:
C:\WINDOWS\System32\BtAutoLaunch.exe
C:\WINDOWS\System32\Btappl.exe

Sur le site, tu clic sur parcourir, puis tu selectionnes le premier fichier en te déplacant dans l'explorateur.
Une fois fait, tu clic sur "Send" pour uploader le fichier.
Une fois l'analyse terminé, copie le résultat dans le bloc notes et fais de même avec le second fichier.
Copie et colle ici, à la suite de ton message le résultat des deux analyses.
