Without a doubt the best choice. Norton has listened to it's customers and vastly improved their product. Set it up, and forget it. It does it's job in the background, silenty, without you having to do a thing. No slowdowns (I use it on a gaming machine and you wouldn't even know it's there since it does not interfere with my computer's speed). The firewall is intelligent. It knows what is safe so you aren't bugged with question after question about what you want to let through. The updates are fast throughout the day and are done in the background. You can download parental controls and anti-spam if you should need them and they are included free. I wouldn't trust my computer to anything else. Try it, you won't be sorry.
