  Formal method techniques provides a suitable platform for the software
development in software systems. Formal methods and formal verification is
necessary to prove the correctness and improve performance of software systems
in various levels of design and implementation, too. Security Discussion is an
important issue in computer systems. Since the antivirus applications have very
important role in computer systems security, verifying these applications is
very essential and necessary. In this paper, we present four new approaches for
antivirus system behavior and a behavioral model of protection services in the
antivirus system is proposed. We divided the behavioral model in to preventive
behavior and control behavior and then we formal these behaviors. Finally by
using some definitions we explain the way these behaviors are mapped on each
other by using our new approaches.
