drvsys.exeopen (Copy of the worm)
drvsys.exeopenopen (Copy of the worm)
The following Registry key is added to hook system startup:
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Run "drvsys.exe" = C:\WINNT\SYSTEM32\drvsys.exe

AVISO PARA TODOS LOS FOREROS_
Em conversación telefonica con ADMIN, me ha informado de la caida del servidor remoto del foro nuevo, ubicado en America
Se está haciendo lo posible para la nueva puesta en marcha, o incluso mientras tanto, habilitar otro servidor aquí de emergencia, para lo que se intentará traspasar los datos.
En cualquier caso, se espera restablecer el servicio del foro en breve.
