I use Norton on all my computers...always have and I'm very pleased with it. Easy to use, easy to get updates, very easy to program auto scans. I had my own graphic design studio for several years and would get hundreds of article, pics etc. each week to include in newspaper and magazine articles and Norton picked up lots of viruses and never let anthing through. Do make sure to get the updates regularly. I have mine programmed for everyday but at least once a week the updates should be downloaded. HTH, Marcye
