这是网页结束时的代码，红色部分以前没有，是木马吧？


<map name="Map">

</map>
<map name="Map2">
  <area shape="rect" coords="274,3,322,21" href="/?list-528.html" target="_blank">

原来是INDEX。ASP文件被更改，

看来有木马呀，怎么找呀，

文件被更改为：

<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<%option explicit%>
<!--#include file="Conn.asp"-->
<!--#include file="KS_Cls/Kesion.Label.CommonCls.asp"-->
<!--#include file="KS_Cls/Kesion.StaticCls.asp"-->
