A question about renewing.

Hi Guys

My Norton 360 anti virus runs out in 2 days and I will be renewing. But when I went to renew through Norton it's come up as paying £65 for it! When I only paid £25 for it when I renewed it last year!!

I had another look around and found that this link here http://uk.norton.com/norton-security-antivirus is one of the best offers that I'm happy to settle with which is £39.99 for the deluxe product for 5 devices for a year.

My main question is, is that from what I can see on the link I posted is that it isn't Norton 360 anymore but is just 'Norton Security Deluxe' I'm just wondering is if I buy this online and not through the Norton application will I have to do a fresh install of Norton or will the days be added on to Norton 360 like they did when I renewed last year?

Thanks Guys.
