专业的人做专业的事情，弓虽病毒AV终结者又有了新的变种！而且似乎弓虽到了逆天！居然可以Ring3级技术来删除AV软件的关键程序，汗颜。不过俗话说“魔高一尺，道高一丈”，金山的病毒专家铁军还是找到了对付的办法，下面演示给大家哈。
以下是详细分析报告：
病毒名： Win32.Troj.AvKiller.hd.212992
病毒利用WH_CALLWNDPROC类型的挂钩将自身注入其他进程
**释放文件**
C:\WINDOWS\system32\nfxphzn.jbt 该文件为kernel32.dll的拷贝
c:\WINDOWS\system32\yqia.btl
该文件为病毒自身的拷贝
**下载文件**
w3.hao5555.com/v3/pic.bmp
w3.hao5555.com/v3/Riched32.dll
w3.hao5555.com/v3/search.asp
w3.hao5555.com/bd.dll
**修改的注册表**
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad]
"xphz"="{1b5f93d7-93d7-0a4e-4e82-93d71b5f93d7}"
[HKEY_CLASSES_ROOT\CLSID\{1b5f93d7-93d7-0a4e-4e82-93d71b5f93d7}\InprocServer32]
@="C:\\WINDOWS\\system32\\yqia.btl"
"ThreadingModel"="Apartment"
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System]
"DisableCMD"=dword:00000001
**挂接函数**
RegEnumValueA
RegEnumValueW -- 目的为隐藏病毒添加的注册表键值
CreateFileA
CreateFileW
-- 目的为保护病毒释放的文件
**卸载组件**
regsvr32.exe /u /s wshom.ocx
病毒自身通过nfxphzn.jbt来调用CreateFileA和CreateFileW函数
病毒注入系统的其他进程后
1> 创建一个线程来保护其添加的注册表键值不被删除
2> 结束杀毒软件进程
3> 通过将ZwCreateFile的前两个字节填0加以破坏
4> 并试图删除以下文件，（主要是杀毒软件和流氓软件清除工具的驱动、程序文件）
"mmskskin.dll"
"KKClean.dll"
"VirUnk.def"
"AntiActi.dll"
"Rsaupd.exe"
"Iereset.dll"
"Libclsid.dat"
"KNetWch.SYS"
"CleanHis.dll"
"WoptiClean.sys"
"kakalib.def"
"libdll.dat"
"kkinst.ini"
"KASearch.DLL"
"KAVBootC.sys"
"Ras.exe"
"iehelp.exe"
"trojandetector.exe"
"KAConfig.DLL"
"KAVPassp.DLL"
"hsfw.dll"
**修改hosts文件为**
hosts文件被修改后，会影响很多杀毒软件和反流氓软件的升级，影响访问相关网站
（注意一下61.152.244.167这个IP，下面发现众多流量很高的站点被劫持到61.152.244.167，可以尝试一下在IE地址栏中输入这个IP，你发现去了cn.yahoo.com）
难道这个病毒在替yahoo做流量？我是不相信的，马云成功在望，不会采取这种流氓手段劫持其它网站的流量，我怀疑是栽赃。或者，中国yahoo的网盟政策被利用了。
