Pete, The software program we use at work is not "friendly" to Norton. We use Trendo Micro's PC-Cillin. I use it at home too and with the "home" version as soon as I boot up if there is an update it tells me but with the "office" version it doesn't do that for some reason. I usually try to remember when I update at home to update at the office but I sometimes forget. I automatically do it once a week though.
