首先病毒会创建如下文件
%Windir%\system\MSAPI.DRV
%Windir%\system\MSSETUP.TSK
%Windir%\system\WINDNSAPI.IME
%Windir%\system\MSWINDOW.DRV
病毒文件插入如下系统进程
msApi.drv %Windir%\system\msApi.drv Process name: explorer.exe
Process filename: %Windir%\explorer.exe
Address space: 0x1ED0000 - 0x1F1E000
windnsapi.ime %Windir%\system\windnsapi.ime Process name: msmsgs.exe
Process filename: %ProgramFiles%\messenger\msmsgs.exe
Address space: 0x10000000 - 0x1000C000
windnsapi.ime %Windir%\system\windnsapi.ime Process name: sdnsmain.exe
Process filename: %Windir%\dns\sdnsmain.exe
Address space: 0x14E0000 - 0x14EC000
windnsapi.ime %Windir%\system\windnsapi.ime Process name: IEXPLORE.EXE
Process filename: %ProgramFiles%\internet explorer\iexplore.exe
Address space: 0x1940000 - 0x194C000
注册表文件分析 ,病毒创建了如下注册表键值并修改

这个是个百度论坛的朋友用虚拟机启动病毒分析到的!和大版主的分析有出入!!
