计算机病毒的工作机理认识及防范措施

Work Mechanism of computer Virus and Preventive Measures

随着计算机技术和信息技术的飞速发展,计算机病毒也在不断地发展和扩散。计算机病毒就像是生物病毒一样,有其自身的病毒体(病毒程序)和寄生体。文章介绍了计算机病毒的工作机理,包括四类机制,即传播机制、运作机制、触发机制、破坏机制,并根据对工作机理的研究提出一系列病毒防范措施。

With rapid development of computer and information technologies, the computer virus is also uninterruptedly developing and spreading. The computer virus, like biologic virus, has its own virus body（the virus programme） and parasitic body. The work mechanisms of the computer virus can be divided into four types, including dissemination mechanism, operation mechanism, trigger mechanism, infection and destruction mechanism etc. And based on the research of the work machanism, a series of preventive measures against the computer virus are proposed.
