I bought a Norton Internet Security 2006 from PC World for 97p (which are selling about £2 + postage on ebay commonly), it comes with a one year subscription. After you registed on the Norton website it will offers you for a free upgrade to Norton 2008 Internet Security (I think the reason is 2006 and 2007 don't support Win Vista so they discontinued them and offers a free upgrade even you don't have Win Vista).
I think Norton provides a good antivirus (correct me if I am wrong), and the Norton Internet Security is retails at £20 - 30 at the market, for less than a fiver I would say it is a bargain.
