Seems I would be installing Norton AV 2006, not NIS, over Systemworks 2002 (my girlfriend ordered a 3-computer pack and misidentified it as NIS). So, the question is, can Norton AV 2002--as part of Systemworks--just be replaced by AV 2006? I would ask Norton, but of course they won't answer questions about 2002 software.
Thanks.
