Merci.

Bonsoir.

C'est étrange car normalement avast vient à bout de ce rootkit qui s'installe dans le Mastezr Boot Record.

Voici une autre méthode d'éradication:

Télécharge mbr.exe de Gmer :
http://www2.gmer.net/mbr/mbr.exe
Sur le bureau.
Merci à Malekal pour le tutoriel

• Désactive tes protections et coupe la connexion. (Antivirus et antispywares, HIPS et autre résident)
• Double clique sur mbr.exe Un rapport sera généré : mbr.log
• En cas d'infection, ce message MBR rootkit code detected va apparaitre.
• Dans le menu Démarrer- Exécuter tape : "%userprofile%\Bureau\mbr" -f en respectant les espaces.
  
• Dans le mbr.log cette ligne apparaitra original MBR restored successfully !
• Poste ce rapport et supprimes-le ensuite.
• Relance mbr.exe et le nouveau mbr.log devrait être celui-ci :

Stealth MBR rootkit detector 0.2.4 by Gmer, http://www.gmer.net

device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
user & kernel MBR OK

Bonjour

Voici le rapport du programme mbr.exe :

Stealth MBR rootkit detector 0.2.4 by Gmer, http://www.gmer.net

device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
MBR rootkit code detected !
malicious code @ sector 0x6fc3dbf size 0x1ca !
copy of MBR has been found in sector 62 !
MBR rootkit infection detected ! Use: "mbr.exe -f" to fix.
original MBR restored successfully !

Je pense que le rootkit a été supprimé car je n'ai plus de message.

Merci pour ton aide.

Voici le 2ème rapport de MBR :

Stealth MBR rootkit detector 0.2.4 by Gmer, http://www.gmer.net

device: opened successfully
user: MBR read successfully
kernel: MBR read successfully
user & kernel MBR OK

merci je crois que j'ai plus rien.

A plus

Bonsoir.

Merci monsieur Gmer.

Tu peux passer la question en résolu.
