OVERVIEW
Modifica archivos para impedir la ejecución correcta de programas y aplicaciones. Elimina archivos para impedir la ejecución correcta de programas y aplicaciones.
TECHNICAL DETAILS
Instalación
Crea las carpetas siguientes:
- %System Root%\ProgramData\Microsoft
- %System Root%\ProgramData\Microsoft\Windows
- D:\RECYCLER
- %System Root%\RECYCLER
(Nota: %System Root% es la carpeta raíz, normalmente C:\. También es la ubicación del sistema operativo).
)Técnica de inicio automático
Se registra como un servicio del sistema para garantizar su ejecución automática cada vez que se inicia el sistema mediante la introducción de las siguientes claves de registro:
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\SessionSysapp
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\SysSvc
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\SystemServices
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\SystemUpdate
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\W32Service
HKEY_LOCAL_MACHINE\SysTEM\cURrentcontrolsEt\
sErvices\W32Log0n
Otras modificaciones del sistema
Modifica los archivos siguientes:
- %User Profile%\Application Data\Microsoft
(Nota: %User Profile% es la carpeta de perfil del usuario activo, que en el caso de Windows 98 y ME suele estar en C:\Windows\Profiles\{nombre de usuario}, en el caso de Windows NT en C:\WINNT\Profiles\{nombre de usuario} y en el caso de Windows 2000, XP y Server 2003 en C:\Documents and Settings\{nombre de usuario}).
)Elimina los archivos siguientes:
- %System Root%\RECYCLER\game.xls
- %System Root%\ProgramData\Microsoft\Windows\Sessionmzz.dll
- %System Root%\ProgramData\Microsoft\Windows\Wmikje.dll
- %System Root%\ProgramData\Microsoft\Windows\UDPsyc.dll
- %System Root%\ProgramData\Microsoft\Windows\DHCPpef.dll
- %System Root%\ProgramData\Microsoft\Windows\Netxxg.dll
- %System Root%\ProgramData\Microsoft\Windows\Servicecry.dll
- %System Root%\ProgramData\Microsoft\Windows\NetCC427.ini
- jpg
- txt
- %Windows%\SoftwareDistribution\DataStore\Logs\edbtmp.log
(Nota: %System Root% es la carpeta raíz, normalmente C:\. También es la ubicación del sistema operativo).
. %Windows% es la carpeta de Windows, que suele estar en C:\Windows o C:\WINNT).)Agrega las siguientes entradas de registro como parte de la rutina de instalación:

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
Reiniciar en modo seguro
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.
