摘要
要使计算机里存储的信息免遭破坏,预防计算机感染病毒或及时发现病毒是非常重要的.本文介绍一种通过检测主引导扇区、引导扇区.中断向量表以及若干文件长度的方法,能及时检测出病毒.在检测程序运行后,确认系统不被病毒感染的情况下,再通过修改INT 13H的中断向量对任何的写盘操作进行提示.只有用户确认后才能执行写操作,从而起到防止病毒感染的作用.
In this paper a method for detecting computer virus by detecting main boot sector, boot sector and the length of some files. The system is confirmed clear after running detecting program. Virus infection is effectively prevented by changing INT13H interrupt vector and giving a note for writing disk. Writing disk will be executed only when it is confirmed.
