Don't Let the Virus Scrooge Spoil your New Year--Dramatic Increases in Computer Macro Viruses Reinforce the Need for Protection

Three To Six Computer Viruses Are Discovered Every Day December Research Shows 158 Documented Macro Viruses, a Significant Increase From 42 in August

CUPERTINO, Calif. -- December 18, 1996 -- Millions of consumers will either buy or receive computers this holiday season. According to researchers at the Symantec Corporation (Nasdaq: SYMC) AntiVirus Research Center (SARC) three to six new computer viruses are discovered every day and, of those, there are an alarming number of new macro viruses. Researchers have documented 158 macro viruses in early December 1996, a 300% increase since August 1996, when there were only 42. Other common viruses at this time of year include Jerusalem.1808 which triggers every Friday the 13th during a calendar year and Joshi.A, triggered on January 5th. The threat of computer viruses is reason enough for consumers to protect their new and existing computer investments with anti-virus software during the new year.

Symantec AntiVirus Research Center (SARC)
SARC is comprised of a dedicated team of virus experts whose sole mission is to provide swift, global responses to computer virus threats, proactively research and develop technologies that eliminate such threats, and educate the public on safe computing practices. As new computer viruses appear, SARC develops identification and detection for these viruses and provides a virus definition update for Symantec’s complete family of anti-virus products, keeping users continuously protected against the latest virus threats. Virus definition updates are available free of charge (other than normal phone and Internet access charges) to users of Norton AntiVirus, and are easily obtained by using LiveUpdate or Intelligent Updater.

The Products
Norton AntiVirus (NAV) 2.0 for Microsoft Windows 95 gives users the security of knowing that they have the most complete virus protection possible, whether they are downloading files from the Internet, opening attached Word documents or accessing floppy disk. This latest version of Norton AntiVirus integrates a wide variety of enhancements, focused on expanded Internet functionality, ease-of-use, consistently and current protection and security. Key features include: LiveUpdate, which provides one button access to the latest virus definition updates; Striker, a next generation scanning engine that scans for the latest and most elusive polymorphic viruses; and Repair Wizard which guides users through the potentially intimidating process of virus elimination.

LiveUpdate
Over 100 new viruses are discovered every month and users need an easy way to keep their anti-virus protection current; LiveUpdate revolutionizes the update process and provides end-users with an easy way to protect against both today’s virus threats and those that will appear in the future – a critical requirement when, on average, 3-6 new are discovered every day. LiveUpdate provides one-button access to the latest virus definition updates. Live Update detects an Internet connection or modem, automatically connects it to a Symantec server, then downloads and installs the latest virus definitions. In addition to receiving Symantec’s free monthly virus definition updates, LiveUpdate may also be used to install software patches and obtain product information. LiveUpdate is a patent-pending technology that will appear in many Symantec products over the coming months and provides a unique way for users to ensure their software solutions are updated. By combining the benefits of LiveUpdate and the wealth of virus expertise and response available from SARC , Norton AntiVirus can promise a user constant virus protection that is always up-to-date. Further, Symantec is proud to be the only major anti-virus company that provides its users virus definitions that are free of charge, easy to obtain and install, and updated monthly.

Striker--Next Generation Polymorphic Virus Detection
A complex polymorphic virus is often very difficult to detect using conventional anti-virus programs, because of the complexity of the encryption. When a user runs an infected program, the virus usurps control of the computer and un-encrypts the main body of the virus. The virus can then take over the computer and potentially damage or destroy important files. Each time it infects a new program, the virus encrypts itself using a different scheme so that it never looks the same to most anti-virus products. Norton AntiVirus overcomes this challenge by creating a “virtual computer” where polymorphic viruses are tricked into view and are then eliminated before they can cause damage.

Repair Wizard
Viruses are often frightening to users who have not encountered them before. Panic measures--like reformatting the hard drive--can cause more problems than the virus itself and may not solve the problem. In response, Norton AntiVirus introduces the Repair Wizard to guide users through the virus clean-up process. The Repair Wizard will provide users with a friendly, comfortable assistant to help them deal with the problem rationally and confidently.
