This article is dedicated to the development of ways to protect computer networks from malicious programs based on fuzzy mathematical models that allow to mathematically is described a sequence of unlawful acts against the protected information system, made with use of malicious program and evaluate security threat level system, depending on the stage of action. Principles for solving mechanisms modeling tasks the impact of malware on secure information systems for evaluation of security threats to their information resources are formed. Also estimate of methods of estimate detection malicious programbased on the aggregation of disparate expertise and fuzzy mathematical models are developed.
