Hi Grahame I have just received this from my isp that is N.T.L see below

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
