Abstract

Computer viruses have the potential to wreak havoc on domestic and industrial computer networks by targeting and deleting important operational programs. Antivirus software is normally installed to detect and remove viruses from infected network computers. In recent times, the compartmental model approach commonly utilized to describe the dynamics of spread for biological viruses in a population has been employed successfully to document the spread of computer viruses in a network. In this paper, we adopt a modified SIRA (Susceptible–Infected–Recovered–Antidotal) model to study the propagation of stealth viruses, and to investigate the impact of antivirus renewal on the dynamics of viral spread in a computer network. The virus-free and endemic equilibria are identified, and a stability analysis is performed on the system. The importance of key parameters on the dynamics of viral spread in the network is illustrated numerically.
