Can i use my existing norton software on a laptop?
Hi Chris, This is Mike from the Norton Authorized Support Team. Norton AntiVirus 2009, Internet Security 2009 and Norton 360 2.0 offer 3-user licenses which allow you to install the software on up to 3 different computers to keep them fully protected from threats. If you have shared drives on your network you can manually scan those drives on the computer that currently has Norton. However the Real-Time scanning feature of all 3 products (called Auto-Protect), and the other advanced detection features, will not be protecting your other computers if you do not install a separate copy of the software on those computers.
