" Dear Customer,


Important information about your BT Yahoo! Internet service


In the next few days you'll be asked to install a critical patch for
your BT Yahoo! Browser software.

This patch must be installed in order for your BT Yahoo! Browser
software to continue working correctly.

You needn't do anything. The patch will be installed automatically and
you should see the following message, or a similar one, once the patch
installation is complete: 'Critical Patch installed successfully'.

Thank you for choosing BT Yahoo! Internet.
