Dear Customer,
Microsoft have contacted us to tell us about a weakness in their Messenger application, which they supply with Windows 2000 and Windows XP operating systems.

If you are using either of these systems your PC could be vulnerable to a computer virus attack and we thought we should make you aware of Microsoft's warning.

Don't worry though, it is easy to fix!

Microsoft have issued a free update to Windows 2000 and Windows XP and below are simple instructions on how to obtain this upgrade and install it on your PC.

We hope you find this email helpful and thank you for being an NTL Internet customer.

Kindest regards

ntl:home Internet Security
