Abstract:In this paper, we establish new sufficient conditions for the infected equilibrium of a nonresident computer virus model to be globally asymptotically stable. Our results extend two kind of known results in recent literature.
Keywords:nonresident computer virus model   permanence   global asymptotic stability   Lyapunov function
