An antivirus program detects a virus by searching code recognized as that of one of the thousands of viruses known to afflict computer systems.An antivirus program also can be used to create a checksum for valuable files on your disk,save the checksums in a special file,and then use the checksums to determine whether files have been modified perhaps by a new virus.Special terminate and stay resident(TSR) program can check for unusual attempts to access vital disk areas and system files,and check files you copy int memory to be sure they are not infected.

英语翻译An antivirus program detects a virus by searching code r
一个杀毒软件判别一个文件是否是一个病毒是通过一个特征码来实现的,这样,数以万计的病毒才能被查出.一个杀毒软件也可以去建立一个可以在磁盘内部存贮一些有价值的系统文件夹,并经过一些核对,来确认是否被一些新的病毒修改过.
TSR这个程序可以帮你检测一些不常用到的系统文件,并对你内存中的这些文件进行检查,来确认有没有被新的病毒修改过.
很乐意为您效劳.
