摘要
计算机病毒是攻击者为了破坏计算机功能或数据而插入的一组计算机指令或程序代码。近年来,计算机病毒数量不断增长,传输媒介变化和互联网的广泛应用,导致计算机病毒感染的对象发生改变,病毒类型也由文件型向网络蠕虫型转变。基于此,主要介绍了计算机病毒的概念、特征、传播途径、病毒防御技术和策略,帮助读者进一步熟悉计算机病毒的危害,提高安全防御意识。
A computer virus is a set of computer instructions or program codes inserted by an attacker to destroy computer functions or data. In recent years, with the increasing number of computer viruses, the change of transmission media and the wide application of the Internet, the objects infected by computer viruses have changed, and the virus type has also changed from file type to network worm type. Based on this, this paper mainly introduces the concept, characteristics, transmission routes, virus defense technology and strategy of computer viruses, to help readers to further familiarize themselves with the harm of computer viruses, and to enhance the awareness of security defense.
