Yes, it's possible to get the full version of the software, but only after you have completed a payment towards to developers of this application, because Norton Security is a shareware product. You can download a trial version, but it will, expire after 30 days making it useless. A single user version will cost you 79.99$ and it can be obtained form the official website. If you want a free solution, I recommend checking COMODO Internet Security. You can obtain a link through the application's page at Software Informer.
