Rutina de infiltración
Infiltra los archivos siguientes:
- %System%\xFile.com
SOLUTION
Step 1
Los usuarios de Windows ME y XP, antes de llevar a cabo cualquier exploración, deben comprobar que tienen desactivada la opción Restaurar sistema para permitir la exploración completa del equipo.
Step 2
Activar el Editor del Registro, el Administrador de tareas y las opciones de carpeta
Para activar el Editor del Registro, el Administrador de tareas y las opciones de carpeta:
- Abra el Bloc de notas. Para ello, haga clic en Inicio>Ejecutar, escriba Notepad en el cuadro de texto y pulse Intro.
- Copie y pegue la siguiente secuencia de comandos:
- Guarde este archivo como C:\RESTORE.VBS.
- Vuelva a hacer clic en Inicio>Ejecutar, escriba C:\RESTORE.VBS en el cuadro de texto y pulse Intro.
- Haga clic en Sí en el cuadro de texto que se muestra para ejecutar el archivo .VBS.
Step 3
Eliminar esta clave del Registro
Importante: si modifica el Registro de Windows incorrectamente, podría hacer que el sistema funcione mal de manera irreversible. Lleve a cabo este paso solo si sabe cómo hacerlo o si puede contar con ayuda de su administrador del sistema. De lo contrario, lea este artículo de Microsoft antes de modificar el Registro del equipo.
