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