Research on the stability and control about propagation patterns of computer virus based on the computer network

摘要

With the increasingly frequent of the informatation and digitization of today, the computer becomes a new means of transport and has spread to every household, but the resulting computer virus has become the key problem to computer users. This paper makes a deep research on network computer virus propagation model. We study from the classification of computer viruses, computer viruses network transmission way, network computer virus propagation model these three aspects, adopts the overall progressive hierarchical structure, interlocking each process, and combined with statistical theory, the circular hierarchy, the concept of tree in graph theory and the thought of clustering analysis, then establishing a new network computer virus propagation model based on hierarchy analysis, finally we put forward that: the variety of the computer virus, the diversification of its transmission way, the specialization of its propagation characteristics, Email invasion, system repair invasion, web browsing invasion are the main network transmission way, although all kinds of computer virus are different, and they are not easy to be antivirus and cleaned, but it is possible to classify the computer virus which has the same characteristics transmission way, so as to further develop defense system and the immune system, which helps to control the spread of computer viruses timely.
