Analysis of Computer Virus Defense Strategy Based on Network Security

Abstract

Computer viruses seriously endanger computer network information security. After the computer is generated, the security of the computer network is attacked by computer computer virus every moment. Computer viruses in computer networks can be brought into the computer through e-mail, downloading software, browsing web pages, etc. The user will unknowingly bring the computer into the computer, causing serious harm to the user's information security. The virus is extremely stealthy, and once the computer is attacked, it is difficult for users to remove it in time, and in the case of undetectable, it will cause incalculable damage to the computer's system. Once discovered, it can cause great damage to the user's computer data. In the actual use process, as people's dependence on the Internet increases day by day, once attacked by the Trojan virus, it will greatly affect people's work and life. In this paper, through the analysis of the propagation mechanism and characteristics of computer network viruses, the corresponding preventive measures are proposed, in order to provide reference for the prevention of computer viruses in China.
