As the global security incidents has risen over the years to ensure that the calculation of security has attracted the world's attention, it is foreseeable, with the computer, Internet, the use of ever-growing popularity, in-depth and guard against computer viruses will be more and more countries are highly valued. This paper introduces a computer virus production and development, discussed the principle of computer virus attacks and attacks. Virus and virus detection methods and examples of computer virus attacks and countermeasures, and methods to eliminate the malicious Web page as an example to explain! From virus infection in-depth analysis of the virus strategy of the complexity of the document, such as memory and network perspective virus infection techniques. At the same time the virus in the computer repair work of a number of commonly used and effective recovery steps and methods. Keyword: computer virus, infection, prevention.随着全球安全事件的逐年增多,确保计算安全已引起世人的关注,可以预见,随着计算机、网络运用的不断普及、深入,防范计算机病毒将越来越受到各国的高度重视。本文简要介绍了计算机病毒的产生和发展,讨论了计算机病毒的攻击原理和攻击方式。以及病毒检测方式和病毒实例,对计算机病毒攻击的防范对策和方法,以消灭恶意网页为例进行讲解!从病毒的感染策略上深入分析病毒的复杂性,从文件、内存和网络等角度讨论病毒的感染技术。同时对中病毒的计算机修复工作提供了一些常用而有效的恢复步骤和方法。 关键字:计算机病毒、感染、防范=Along with global security incident's yearly increase, guaranteed that the computation safe has aroused common people's interest, may foresee, along with the computer, the network utilization popularizes unceasingly, thoroughly, will guard against the computer virus to receive various countries to take seriously more and more. This article introduced briefly computer virus' production and the development, discussed computer virus' attack principle and the forms of defensive action. As well as the virus detection mode and the viral example, to the computer virus attack's guard countermeasure and the method, take eliminate the malicious homepage to carry on the explanation as the example! From virus's infection strategy thorough analysis virus's complexity, from angle discussion virus's and so on document, memory and network infection technologies. Meanwhile has provided some commonly used and the effective restoration step and the method to the virus's computer recovering. key words: Computer virus, infection, guard
