Computer Virus-Antivirus Co-evolution

Carey Nachenberg - Symantec

Apr 03, 2002


Over the past twenty years, computer viruses have evolved from simple computer programs capable of spreading on a single PC to complex software worms which can ravage global networks. Much of the evolution of new computer virus threats has come from two major sources. First, as popular new computing platforms become available virus authors seek to exploit these platforms. Second, the co-evolution of anti-virus technology has spurred the development increasingly powerful, more complex computer virus threats.

This talk examines the evolution of computer viruses, with respect to detection-avoidance, and considers the future virus threats we are likely to encounter. In addition, it takes an in-depth look at anti-virus technologies, present and future, to better understand how our computer countermeasures will have to change to provide adequate protection against tomorrow's viruses. The talk focuses on some of the more interesting algorithms and systems which have been used or are proposed in the battle to detect and repair these increasingly complex virus threats.
