SUMMARY
=======

Although e-mail provides an efficient and easy way to share information,
you may run the risk of unknowingly opening an attachment that starts a
program or executable code that could cause damage to your computer.

Microsoft provides a security feature to provide you with a warning before
attachments are opened. Microsoft encourages all MSN, The Microsoft
Network, members who are using Microsoft Exchange versions 4.x or 5.x,
Windows Messaging, or Microsoft Outlook 97 as their e-mail program to
download the Mail Attachment Security Add-on for Microsoft Mail Clients.
To do so, visit the following Microsoft Web site:

   http://www.microsoft.com/security/bulletins/mailaddon.asp

If you use Microsoft Internet Mail and News, you can obtain a similar mail
security attachment add-on by installing Microsoft Internet Explorer 3.02.
To obtain Internet Explorer 3.02, visit the following Microsoft Web site:

MORE INFORMATION
================

The Mail Security Attachment Add-on protects you from opening attachments
that have been altered to start a program or executable code that might
damage your computer. If the add-on detects that an attachment has been
changed, you receive a warning message. You are then prompted to choose
whether or not to open the attachment. In addition, you have the ability
to bypass the warning for selected file types that you feel comfortable
opening without a warning, as well as for executable code that is signed
using Authenticode.

Authenticode is a technology that software publishers use to sign their
products, helping to ensure that content and files you download from the
Internet are authentic and safe. For additional information about
Authenticode, please see the following article in the Microsoft Knowledge
Base:
