  Soluzioni

Motore di scansione minimo: 9.850

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

Identificar y terminar los archivos detectados como PUA.Win32.ByteFence.D

[ learnMore ]
  1. Para los usuarios de Windows 98 y ME, puede que el Administrador de tareas de Windows no muestre todos los procesos en ejecución. En tal caso, utilice un visor de procesos de una tercera parte (preferiblemente, el Explorador de procesos) para terminar el archivo de malware/grayware/spyware. Puede descargar la herramienta en cuestión aquí.
  2. Si el archivo detectado aparece en el Administrador de tareas o en el Explorador de procesos, pero no puede eliminarlo, reinicie el equipo en modo seguro. Para ello, consulte este enlace para obtener todos los pasos necesarios.
  3. Si el archivo detectado no se muestra en el Administrador de tareas o el Explorador de procesos, prosiga con los pasos que se indican a continuación.

Step 3

Eliminar este valor 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.
