My edition of Norton is about to expire. I'm considering AVG or maybe another anti-virus program. Is there anything special I need to do before installing and/or trying out a different anti-virus program. Do I need a special tool to remove all traces of Norton? Actually, can I install the new program before uninstalling Norton? I would deactivate Norton, but I'm wondering if it would be easier to keep Norton on my system in the event that I don't like the new program and choose to return to Norton. Katrina
