I would consider this fake and certainly wouldnt be clicking any links in it or attachments. If ur certain of its validity then it is no better than spam and looks like a desperate attempt by those morons to try to stop thier customers getting virused up with things that shows thier security programs up for the sh!t they are, its probs the result of a lot of thier customers complaining that they are using p2p and norton isnt finding viruses they have downloaded, so norton ar trying to go to the root and stop people getting the virus by default (not infecting themselves) rather than upgrading thier program like they should to be able to deal wiv the threats. Norton is the critical risk. If your very pc experienced fine use what ya like every one has thier tried and tested software, but if ur a noob or someone who has only ever used norton get a decent av.
