This program is exceptional, all it takes is for people to install it ON A SYSTEM THAT CAN COPE with the small amount of system resources it does use and you will find that protection is great!

I honestly do not know (or even have known) one person who kept or willingly purchased Norton. It definitely does not provide the best protection from viruses, and tends to cause a lot of crashes and issues with other applications. I gave it a chance myself once, and my computer completely froze and had to be restarted- something that has not happened to me in years on a quality, well-maintained computer. Norton may have been good at one point, but now they're just relying on their big name to stay in business.
