Next-generation viruses present new challenges

Computer technology has advanced in many ways, but not all of them have been welcome. One of the more undesirable has been the ongoing advance of virus technology. Taking advantage of emerging computer technologies and techniques, virus writers come up with new ways to defeat existing security software, infect computers, cause damage, and spread their malicious creations. This has become evident recently with the emergence of several innovative and potentially harmful viruses, e.g., remote control viruses, peer-to-peer viruses, and open source viruses.
