¡Parche FALSO. Cuidado!

Hola

Acabo de recibir un correo de wfdjghzna@confidence.ms.com conteniendo un adjunto que parecia llamarse INSTALLATION97.exe y que lógicamente se ha encargado de eliminar el antivirus de nuestra organizacion de Exchange.

Microsoft NUNCA envia por correo parches adjuntos a lista de distribucion alguna. Los mensajes generados con alertas de seguridad se envian en TEXTO PLANO y son siempre contrastables en http://www.microsoft.com/technet/security/bulletinsandadvisories/default.mspx
