Microsoft Active Protections Program (MAPP)
===========================================
To improve security protections for customers, Microsoft provides
vulnerability information to major security software providers in
advance of each monthly security update release. Security software
providers can then use this vulnerability information to provide
updated protections to customers via their security software or
devices, such as antivirus, network-based intrusion detection
systems, or host-based intrusion prevention systems. To determine
whether active protections are available from security software
providers, please visit the active protections Web sites provided by
program partners, listed at
http://www.microsoft.com/security/msrc/collaboration/mapp.aspx.

Recognize and avoid fraudulent e-mail to Microsoft customers:
=============================================================
If you receive an e-mail message that claims to be distributing
a Microsoft security update, it is a hoax that may contain
malware or pointers to malicious Web sites. Microsoft does
not distribute security updates via e-mail.

The Microsoft Security Response Center (MSRC) uses PGP to digitally
sign all security notifications. However, PGP is not required for
reading security notifications, reading security bulletins, or
installing security updates. You can obtain the MSRC public PGP key 
at
