Rutina de infiltración
Infiltra los archivos siguientes:
- %System%\users32.dat
(Nota: %System% es la carpeta del sistema de Windows, que en el caso de Windows 98 y ME suele estar en C:\Windows\System, en el caso de Windows NT y 2000 en C:\WINNT\System32 y en el caso de Windows XP y Server 2003 en C:\Windows\System32).
