Abstract :
Inspiration form biological immune mechanism, this article gives the formal definition of computer virus in the gene model. Based on immune genetic algorithm, a evolution model of computer virus is proposed, and also the evolution operators which include selection operator, crossover operator, mutation operator and immune operator are established. The simulation experiments were conducted and it indicates that computer viruses and biological viruses have the same natural features, it also has a self-replicating, self-construction and self-evolution of biological characteristics. The evolution model of computer virus can provides research thinking for anti-virus technology to improve and enhance, especially on detecting and preventing unknown viruses or mutations of known virus.
