摘要
计算机病毒是一种可以感染可执行文件的程序。当可执行文件被感染后,它就开始复制自己并且感染其他的文件。当然这些并不需要你的同意。病毒通常有两个阶段,复制阶段和破坏阶段。计算机病毒现在能够如此迅速的传播应该得益于网络的普及和电子邮件的流行。
A Computer Virus is a program that infects executable files. When the infected file is executed, the virus replicates itself and spreads by infecting other executable files, Of course, the virus will try to infect your computer without your knowledge or permission. A virus generally has two phases; An infection phase where the virus reproduces extensively, and an attack phase where it does the damage it was programmed to do Computer viruses now can spread very rapidly due to file sharing technologies such as the the internet and email.
