Bonjour,
depuis quelques jours, je vois des fichiers qui se multiplient comme des champignons sur mon PC et ma clé USB. Tout a commencé après qu'une collègue ait branché sa clé sur mon poste. Depuis, je retrouve un autorun.inf et des fichiers .exe persistants sur ma clé; quand je les efface, ils reviennent tout de suite.
Ces fichiers executables ont des noms à coucher dehors: btdxrvaa.exe, puvheqby.exe...
avast ne me signale rien du tout.
Est-ce que vous pourriez m'aider à faire déguerpir ces intrus??
Je joins une copie du log hijackthis de mon poste.
Merci d'avance!!
