Keeping Up With SARC

September Virus Update Now Available

How can you keep your software safe from the latest macro, file, and boot sector viruses? Just download 09NAV97.EXE from the SARC website or click your LiveUpdate button to obtain this support.

Intelligent Updater News

For your convenience, Intelligent Updater is now available in two forms. One is a single all-inclusive file, and the other is split into packages sized to fit on floppy disks. Either way, you get the same detection, repair, and support.

Rescue Disks

You may have experienced problems building rescue disks after updating with the July 1997 virus definition set. The virus definition files were too large to fit on a single floppy disk. Well, SARC has some great news! The September 1997 LiveUpdate package contains a solution to the problem that works for both Norton AntiVirus 2.0 for Windows 95 and Norton Utilities 2.0 for Windows 95.

The solution is to build a subset of the virus definitions and copy those smaller files to the floppy disk. Only wild viruses--those that pose a direct threat to the world at large--are copied. The remaining viruses (the majority) are classified as "Zoo" samples. SARC has seen them, but to our knowledge, no one has been infected by them, anywhere in the world. Obviously, protection from the wild viruses is much more important.

To summarize, the September 1997 virus definition set is still a complete compilation of virus detection and repair files. However, from now, on the rescue disk will include only the most threatening viruses.

SARC is working on a similar solution for use with Intelligent Updater, supporting Norton AntiVirus 3.0 for DOS/Windows 3.1 and Windows 95. Expect it online in the near future!

Symantec Ships Norton AntiVirus for Firewalls

On July 14, 1997, Symantec shipped Norton AntiVirus for Firewalls. As part of the Norton AntiVirus product line, this new program provides comprehensive virus protection for corporations with compatible firewalls. The new product works by catching and destroying Internet-borne viruses before they invade corporate computer networks.

Supported by industry-leading firewall vendors, the program operates in conjunction with an existing firewall to provide an unparalleled corporate gateway security solution. NAV for Firewalls includes an unrivaled degree of administrative flexibility and control at minimal expense to network throughput. Combined with the recently released Norton AntiVirus Internet Email Gateways, Symantec delivers complete protection for corporate networks.

NAV for Firewalls minimizes network throughput degradation by intelligently scanning only suspicious traffic for viruses. An HTML user interface allows remote configuration. Based on the revolutionary product architecture developed jointly by Symantec and Check Point Software Technologies, the new program will be integrated seamlessly into existing corporate firewalls.

Symantec's partners include Check Point Software Technologies, Trusted Information Systems (TIS), Secure Computing, CyberGuard Corporation, and Milkyway. In addition, Symantec plans to implement support for Microsoft's Proxy Server later this year. Together, these vendors hold approximately 50 percent of the firewall market according to market researcher International Data Corporation (IDC.)
