New inbound port blocking to prevent worm intrusions; faster preinstallation scans; improved interface.
Doesn't include a full-fledged firewall; real-time scanner doesn't look for spyware.
What's it for:
Protection from numerous Internet menaces, including viruses, worms, Trojan horses, and spyware.
Who's it for:
PC users who already run a firewall; current Norton AntiVirus 2004 users looking to upgrade.
Multiple seat licenses let you protect all of the computers in your office.
A good firewall.
The bottom line:
Norton AntiVirus 2005 is a tenacious virus fighter that, given its premium price, should also--but doesn't--include a firewall. It's a good bet for Norton users who want to upgrade, though.
