Detecting Complex Viruses

The purpose of this paper is to examine the difficulties of detecting complex viruses, including polymorphic, metamorphic and entry-point obscuring viruses. Whether or not an anti-virus technology can detect these viruses can be a useful metric to consider when evaluating AV products. In this article, we will show how complex viruses can offer an entirely different threat to organizations. It is important to step into the world of complex viruses by defining what a metamorphic, polymorphic, and entry-point obscuring virus is, understand when it is considered a real threat, and then see some real-life examples of complex viruses that have been discovered. This will lead into a discussion on the limitations of current anti-virus engine technology, and then finally, we will try to gauge the importance of detecting these complex viruses accurately, and in a timely fashion.

This should be considered a well written 101 on viruses and cyber security generally... thank you for the share!
