Step 2
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 3
Note that not all files, folders, and registry keys and entries are installed on your computer during this malware's/spyware's/grayware's execution. This may be due to incomplete installation or other operating system conditions. If you do not find the same files/folders/registry information, please proceed to the next step.
Step 4
Identificar y terminar los archivos detectados como Trojan.Win32.PRIVATELOADER.YXDBSZ
- 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.
- 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.
- 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 5
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.
- In HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\{SID}Machine\SOFTWARE\Policies\Microsoft\Windows Defender\Extensions
- exe = (default)
- exe = (default)
Step 6
Restore this modified registry value
Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this only if you know how to or you can seek your system administrator’s help. You may also check out this Microsoft article first before modifying your computer's registry.
