Do you know if there are free download for Norton Internet Security anti-virus?  

Your best bet would be any of the torrent sites (like mininova.org or demonoid.com).

Why on earth do you want Norton? In my experience with it I've not found it to be very effective. You'd do better with AVG, AVAST or Zonealarm, all of which are free downloads and all of which are way better than Norton.

I have tried norton but I have noticed that its not very effective. What I am using right now is AVIRA. It is very good and have not found any problem with it so far. It is also free to download. You can get it at www.freeav.com, just choose the PERSONAL one since it is free. I have been using it for a year already. Most of my friends who have tried it have stick to eat and swore that they to find it very effective. Just try it out. Make sure to uninstall your present anti virus before installing avira.

You can download KASPERSKY. This is a good internet security software.

download from site and then search for keys

I've used Norton's system works, AVG and Avast and I feel Avast is the best I have used. It is really one of the best in my opinion you can get a free copy off of Avast's website I haven't The pro edition but the Free version must be just as good. Good luck!
