%X This paper proposed a modified SAIC (susceptible, antidotal, infected, contaminated) model with optimal control, which was intended to keep both the number of infected nodes and the systemic cost levels low. By using the relevant principles and methods in optimal control theory,it proved the existence of an optimal control. In addition, characterized the optimal control by an optimality system. Numerical simulations show that the spread of computer virus can be controlled effectively with proper control strategies. The proposed method is expected to become a useful tool in controlling the spread of computer virus.
