Internet Security Barrier is a suite of three applications to give you complete privacy, anti-virus, intrusion, and filtering protection. NetBarrier is designed to protect the Macintosh user from the perils of the Internet. Its four-level line of defense provides optimal security so that you can use the Internet without leaving yourself vulnerable to its dangers. VirusBarrier is an anti-virus solution that eliminates all known viruses from your Mac, both system and macro viruses. Personal Backup backs up your data, either automatically or manually, to removable media (such as recordable CD-Roms or Zip cartridges), to partitions on your hard disk, to network volumes, to an iDisk, to external hard drives (USB, Firewire or SCSI) or to disk image files. You can choose to backup specific folders or entire volumes or hard disks, and run each backup with a single mouse-click.

NetUpdate can be used to check if updates to any of these programs are available. It can carry out automatic checks, at the frequency you choose, or it can be used to make manual checks whenever you wish. With just one click, you can check to see if there are new versions of any of the programs, or updated virus definitions for VirusBarrier. If updates are available, you can download them quickly and easily, and make sure you always have the latest versions to keep your computer safe.
