Please contact your Antivirus Vendor for additional details on this virus.

PREVENTION:

to improve the security in Outlook and other Office programs.

To ensure you are using the latest version of Office click here:
http://office.microsoft.com/ProductUpdates/default.aspx

By default, Outlook 2000 pre SR1 and Outlook 98 did not include these
updates, but it can be obtained by installing the Outlook E-mail Security
Update. More information about the Outlook E-mail Security Update can be
found here: http://office.microsoft.com/Download.../Out2ksec.aspx

Outlook Express 6 can be configured to block access to potentially-damaging
attachments. Information about how to configure this can be found here:
http://support.microsoft.com/default...;en-us;Q291387

Outlook Express all other versions: Previous versions of Outlook Express do
not contain attachment-blocking functionality. Please exercise extreme
caution when opening unsolicited e-mail messages with attachments.

Web-based e-mail programs: Use of an application-level firewall can protect
you from being infected with this virus through Web-based e-mail programs.

RECOVERY (UPDATED):

If your computer has been infected with this virus, please contact your
preferred antivirus vendor or Microsoft Product Support Services for
assistance with removing it.
A potential symptom of infection with the MyDoom.B Virus is that you are you
unable to visit your Antivirus vendors website or various Microsoft websites
such as support.microsoft.com or windowsupdate.microsoft.com. If you are
experiencing these symptoms please use the following manual commands to
enable access to these websites:

Go to Start Run and type cmd to get a command prompt. Within the command
prompt, type the following commands:

- del /F %systemroot%\system32\drivers\etc\hosts [enter]
- echo # Temporary HOSTS file >%systemroot%\system32\drivers\etc\hosts
[enter]
- attrib +R %systemroot%\system32\drivers\etc\hosts [enter]

On Windows NT, you must reboot after typing these commands.

On Windows 2000, Windows XP, and Windows 2003, you do not need to reboot.
Instead, you must type the following command:
- ipconfig /flushdns [enter]

If you have any questions, you should contact Product Support Services in
the United States at 1-866-PCSafety (1-866-727-233. International
customers should contact their local subsidiary.

Thank you,

PSS Security
