Overview of real-time antivirus scanning engines

Abstract

Malicious code is one of the biggest problems in the world of networks. There exist various methods and techniques stating that they protect user. For quite some time the most popular protection method against viruses was on-demand scans. Various attempts to implement on-access or real-time scanning mechanisms were either consuming too much valuable system resources such as memory or offering too little protection. In this article we review a number of open-source and patented methods of real-time antivirus scanning describing their methods of work, advantages and disadvantages. Such kind of research is needed in order to gather in one article and to demonstrate the methods and attempts to successfully implement real-time scanning mechanism and to overview this sphere of application development. In what direction could the next step in developing real-time antivirus scanners be made and what problems are common in such cases.
