Symantec Combats New and Unknown Boot-Sector Viruses with Exclusive Bloodhound Boot Technology
Norton AntiVirus Offers Comprehensive Protection Against New and Unknown File, Macro and Boot-Sector Viruses
Cupertino, Calif. --January 21, 1998--Symantec Corporation (NASDAQ: SYMC), the world's leading supplier of anti-virus software, today announced that the Symantec AntiVirus Research Center (SARC) has developed Bloodhound Boot heuristic technology to combat the threat of new and unknown boot-sector viruses. Bloodhound Boot joins Symantec's Bloodhound for Files and Bloodhound-Macro technologies to provide Norton AntiVirus users with the industry's most comprehensive virus protection against new and unknown boot, file and macro viruses.
Bloodhound Boot is included with the January virus definitions at Symantec's Web site (http://www.symantec.com). Norton AntiVirus users can download and install the new technology by simply running the LiveUpdate feature.
While the prevalence of macro viruses has grown exponentially in the last two years, boot-sector viruses still account for four out of the 10 most common computer virus infections. In fact, boot-sector viruses are a leading cause of corruption on computers with the Microsoft Windows NT operating system.
"The risk of infection and damage from viruses is significantly greater today than ever before," said Enrique Salem, vice president of Symantec's Security and Assistance Business Unit. "Boot-sector viruses, like file and macro viruses, can have a profound effect not only on system reliability but on user productivity. Our Bloodhound technology ensures that our customers are protected against today's known viruses as well as tomorrow's new ones."
The Boot-Sector Virus
A boot sector of a diskette or hard drive contains information about the size and organization of the disk and is used by the computer's operating system to determine how to access the diskette or drive. Boot-sector viruses typically invade a PC through an infected floppy disk that is left in a drive while the PC is started. These viruses replace the critical boot sector program used to start the computer with their own malicious program logic.
The most common technique to detect boot-sector viruses is known as signature scanning. Typically, when an anti-virus vendor receives a new virus, it analyzes the virus and extracts a virus fingerprint or a signature. If the anti-virus program locates a virus signature in one or more of your boot sectors, it can identify the virus and take steps to repair the infection. Viruses that have not yet been analyzed are invisible to such anti-virus software. Signature scanning is not only incomplete but, because it requires users to maintain frequent contact with their anti-virus vendor, it can also be costly and time-consuming.
Bloodhound Boot Features
Bloodhound Boot is a complete departure from traditional signature scanning technology to detect virus infections. Rather than using signatures, Bloodhound Boot uses Symantec's exclusive heuristic technology to detect boot-sector viruses by inspecting boot sectors for virus-like behavior. Bloodhound Boot scrutinizes the boot sector's overall structure, its programming logic or computer instructions and a number of other attributes to determine the likelihood that the boot sector is infected by a virus.
Norton AntiVirus will notify users when Bloodhound Boot has found a new or unknown boot-sector virus. If users get this notice, it is critical that they send in a sample of the virus to SARC for comprehensive analysis so that they may receive the most up-to-date anti-virus solution. Because of the varying types of damage boot-sector viruses can cause, they cannot be repaired in a generic fashion and must be submitted to SARC for analysis. Users can find instructions on how to submit virus samples to SARC on the Symantec Web site (http://www.symantec.com/avcenter/submit.html) or by calling Symantec's technical support.
