Thanks to Shadow Master for posting this in the forums.
There is a MSN virus getting around, it takes over MSN/Windows Messenger and sends this out to all your contact list and infects them also.
The message is: "URGENT - Go to https://www.rjdesigns.co.uk/cool Now!"
If you click on the link (I did a couple of times DOH!) :( It will take over your Messenger account and send the message to all your contacts. Norton Antivirus didnt pick out a trojan from my machine, but Pop Up Stopper from Panicware DID prevent a javascript popup that takes over your screen.
At the time of posting I am unaware of the additional affect it has on Messenger or if you need to run a full virus scan (although its recommended if you clicked the link)
On a positive note I have been told that nobody received the message from my contact list so I guess the code on the page is not entirely good if a popup stopper stops it in its tracks.
We advise you NOT go to the above bolded address because it can infect MSN.
