Depends upon your intended use. For home users, Norton Antivirus/SystemWorks is probably fine. But for corporate deployments, Symantec Antivirus Corporate Edition is the way to go. Why?
Corporate Edition
- Doesn't require yearly subscription renewals
- Clients can be deployed with Group Policy, SMS, or scripted - so you don't have to visit every workstation.
- All of the clients can be managed over the network from a single console.
- What's that? New email worm out and you want definitions NOW? Just update the primary server, and everything else updates too.
- Decided that nightly scans at 2 am are interrupting backups, and you want to move the scan to 4 am? You can do that for ALL of the machines from the console with just a couple of clicks.
- Console view shows All of your clients, their definition versions, their scan dates, etc. so you don't have to worry about whether a machine has a broken LiveUpdate - you'll know.
