To say the same as other reviewers would not be very productive, but I do need to reiterate a few points that I have found over the 8 or 9 years I have used Norton for. 1. yes Norton is a little hungry on memory, but not as much as it use to be and it has run on every machine I have had without problem. 2. To renew with Norton is a definite no no. As another reviewer has said, it will cost you twice as much to renew the license via the Symantec renewal procedure as it does to purchase a completely new version from Amazon, why it is so much cheaper to purchase new I will never understand, but that's how it is, all you need to do is input the new license code and its up to date, that is as long as it is the same version ie 360 and you have updated your old version first. 3. Yes Norton is probably on of the best AV/Firewalls on the market, and will keep you safe plus it also provides you with an online backup service that also safely stores all your log on passwords and it will automatically fill them in for you when you go to a website when you use the "Password Vault", believe me I would be lost without it. Set up your online account, if you are a new user and everything is straight forward after that, there is online help at the click of a button, it will auto check for any faults that might arise in the program to make sure all is as it should be. A very good bit of software, but remember it can only be as good as the user lets it be, when you click "yes" to download and ignore any warnings that Norton gives then the problem is yours because you have bypassed any protection. To finish all I can say is that Norton is updated online, if you have problems and need to re install, that is done online via "My Account" so you can take the label off the box use the disc as a coaster and put one of your favourite DVDs in the box. They also look quite nice all lined up on a shelf, useless but nice. I highly recommend this product.
