Propagation of Computer Virus under Human Intervention : A Dynamical Model

Abstract EN

This paper examines the propagation behavior of computer virus under human intervention.

A dynamical model describing the spread of computer virus, under which a susceptible computer can become recovered directly and an infected computer can become susceptible directly, is proposed.

Through a qualitative analysis of this model, it is found that the virus-free equilibrium is globally asymptotically stable when the basic reproduction number R0≤1, whereas the viral equilibrium is globally asymptotically stable if R0>1.

Based on these results and a parameter analysis, some appropriate measures for eradicating the spread of computer virus across the Internet are recommended.
