Merci.

Bonjour,

Apparemment ok.

Télécharge Gmer.
Dézippe le dans un dossier ou sur ton bureau.

Déconnecte toi d'Internet puis et ferme tous les programmes.
Double-clique sur Gmer.exe.

IMPORTANT: Si une alerte de ton antivirus apparaît pour le fichier gmer.sys ou gmer.exe, laisse le s'executer.

Clique sur l'onglet rootkit.
A droite, coche Files et Services.
Clique maintenant sur Scan.

Lorsque le scan est terminé, clique sur Copy.

Ouvre le Bloc-notes puis clique sur le Menu Edition / Coller.
Le rapport doit alors apparaître.
Enregistre le fichier sur ton bureau et copie/colle le contenu ici.

Merci de ta réponse, voici le rapport :

GMER 1.0.14.14536 - http://www.gmer.net
Rootkit scan 2008-09-22 19:11:33

---- Disk sectors - GMER 1.0.14 ----

Disk \Device\Harddisk0\DR0 sector 16: copy of MBR

---- EOF - GMER 1.0.14 ----


Voilà j'espère que je n'ai pas fais d'erreur.

Et entre temps j'ai refais un scan avec avira et il a repéré un cheval de troie. Mais j'ai du interrompre le scan pour utiliser Gmer.
Donc voici le rapport d'avira :
