Symantec First to Deliver Repair for PowerPoint Viruses, Including O97M.Tristate Cross-Infecting Microsoft Office Macro Virus
Complete Virus Definition Set Now Available for Norton AntiVirus Users via LiveUpdate
Cupertino, Calif. May 20, 1999 - Symantec Corporation
(Nasdaq: SYMC), the world leader in utility software for business and personal
computing, today announced a complete virus definition set is now available to
detect and repair PowerPoint viruses as well as the prolific O97M.Tristate macro
virus, which cross-infects Microsoft Office applications. The new virus
definitions can be downloaded for all Symantec anti-virus products via
LiveUpdate or from the Symantec AntiVirus Research Center (SARC) download page
on the Symantec web site (www.symantec.com). While other anti-virus vendors
provide detection-only capabilities, Symantec is first to provide repair of the
viruses on all platforms.
"As the number of PowerPoint and cross-infecting viruses increases, it is
critical that computer users have a quick and reliable method of protecting
their valuable data and systems from the potentially destructive effects of this
code," said Enrique Salem, vice president of Symantec's Security and Assistance
Business Unit. "To that end, Symantec is pleased to be the first software vendor
to offer a virus definition set that provides both detection and repair."
Creating a macro virus that can cross-infect different Microsoft Office 97
applications is becoming more common among virus writers. The O97M.Tristate
virus is evidence that these viruses are no longer limited to research labs, but
are beginning to move into general circulation. Since May 7, Symantec has
received 132 submissions of the O97M.Tristate macro virus, alias
O97M.Triplicate, via Norton AntiVirus' Scan and Deliver mechanism, making the
cross-platform virus the eighth most common virus submitted to SARC. The macro
virus, found in the wild, infects Microsoft Word 97 documents, Microsoft Excel
97 spreadsheets, and Microsoft PowerPoint 97 presentations. For more information
about the O97M.Tristate virus, refer to the Symantec Virus Encyclopedia at
Norton AntiVirus users can protect their systems against the potential spread of
O97M.Tristate and other PowerPoint or cross-infecting viruses by using
LiveUpdate to download the latest set of virus definitions from the Symantec web
site. In addition to virus definitions, the LiveUpdate feature also re-programs
Symantec's anti-virus software using the company's Norton AntiVirus Extension
(NAVEX) technology. This modular virus-scanning engine lets SARC engineers
quickly update and seamlessly update the scanning engine during normal virus
definition updates. It's the only solution of its kind available to users of
anti-virus software today.
