Bonjour

Télécharge SDFix (créé par AndyManchesta) et sauvegarde le sur ton Bureau.

http://downloads.andymanchesta.com/RemovalTools/SDFix.exe

Double clique sur SDFix.exe et choisis Install pour l'extraire dans un dossier dédié sur le Bureau.

Redémarre ton ordinateur en mode sans échec en suivant la procédure que voici :
• Redémarre ton ordinateur
• Après avoir entendu l'ordinateur biper lors du démarrage, mais avant que l'icône Windows apparaisse, tapote la touche F8 (une pression par seconde).
• A la place du chargement normal de Windows, un menu avec différentes options devrait apparaître.
• Choisis la première option, pour exécuter Windows en mode sans échec, puis appuie sur "Entrée".
• Choisis ton compte.

Déroule la liste des instructions ci-dessous :
• Ouvre le dossier SDFix qui vient d'être créé dans le répertoire C:\ et double clique sur RunThis.bat pour lancer le script.
• Appuie sur Y pour commencer le processus de nettoyage.
• Il va supprimer les services et les entrées du Registre de certains trojans trouvés puis te demandera d'appuyer sur une touche pour redémarrer.
• Appuie sur une touche pour redémarrer le PC.

• Ton système sera plus long pour redémarrer qu'à l'accoutumée car l'outil va continuer à s'exécuter et supprimer des fichiers.
• Après le chargement du Bureau, l'outil terminera son travail et affichera Finished.
• Appuie sur une touche pour finir l'exécution du script et charger les icônes de ton Bureau.
• Les icônes du Bureau affichées, le rapport SDFix s'ouvrira à l'écran et s'enregistrera aussi dans le dossier SDFix sous le nom Report.txt.
• Enfin, copie/colle le contenu du fichier Report.txt dans ta prochaine réponse sur le forum

merci beaucoup je vais le faire...
