Kaspersky Internet Security 2009 1 year 5 user licence. I saw this at The Works in Feltham and picked up a couple. They still had a few left.
Its not on their website so I don't know if the offer is nationwide.
This was the cardboard box version, and allows you to upgrade to their latest 2010 version.
Please note they also have the 1 user and 3 user at the same price.
