Right guys, I have found a blog belonging to the Phorm Comms Team. For those in the know, type blog.phorm.com into robtex - you will notice that the IP is one of Phorms.
Visiting
http://blog.phorm.com is not an issue. However, visiting by IP flags a serious security alert with Norton.
(To mods: The site is in the public domain - and this is not given bad advice, on the contrary it is alerting users to a potential risk, which may be nothing knowing norton)
