It needs less hardware resources than before and it is really easy to install and manage! I especially like that you have to wait once more until a full system scan has been completed. For the 2nd time that takes only a fraction of the previously required time. Why? Because Norton is now able to see which files have been already tested or have not changed. And these files were previously clean, they will not be re-examined. Thus, the test speed increased enormously.
So I can really say is that it was definitely worth it, the new Norton Internet Security 2009 Buy.
Who is not sure, yet can indeed download a demo on the pages of Symantec.
In short: a good Internet Security Suite!
