Bonjour,

Mon antivirus me signale la présence d'un Hacktool que je n'arrive pas à supprimer. Après quelques recherches, j'ai trouvé diverses infos, je me permets donc de vous transmettre mon log ci-après. Pac contre je surfe avec mozilla, et le log me renvoie IE.

D'avance merci

J'ai installé HijackThis comme il est précisé sur les différents forums, et j'obtiens ce log:
