病毒码

目前常用的杀毒技术是利用病毒码扫描方法，检查文件是否含有病毒。但是这种传统的杀毒技术只能对已知病毒进行有效查杀，对未知病毒却毫无办法。

The commonly used virus-killer technology makes use of the method of virus code scanning to check whether the file contains virus , but this traditional technology can only find out and kill the known virus effectively and do nothing with the unknown ones .
