Before the availability of free internet security protection through my AOL membership, I purchased Norton for use on my home PC.  For the price I paid, you would think that it would be something you could use for years and years, but this is not the case.  It works great and I never had a single issue or sneak attack break through it while I used it, but when you buy it, you only get updates for one year after purchase.  After that, you have to pay for the updates.  I thought that was a tricky way to get more money out of people that you have already sold software too and did not renew my updates with them once they expired.  I would recommend this software to anyone who is willing to continue to pay for updates or has no option but to do this.  It works well and will protect your systems.

Too big for my PC. I have friends that use Norton and all of them complain because their computer slows down with Norton, they can't have a regular internet speed.
