Norton AntiVirus version 5.0 has new features that let you quarantine infected files and get help directly from Symantec researchers. Also, it automatically protects you against viruses and malicious ActiveX and Java applets. As always, Norton AntiVirus can run constantly in the background to keep your computer safe from viruses that might come in from email attachments, Internet downloads, floppy diskettes, software CDs, or a network. And it can be scheduled to automatically retrieve new antivirus definitions from Symantec as often as once a week.
