病毒分析：
1.病毒运行后检测是否为被调试，如果是,则遍历进程查找ollydbg.exe，ollyice.exe，c32am.exe，peditor.exe，importrec.exe,loadpe.exe等进程并将其结束进程。
2.关闭以下服务schedule,appmgmt,srservice,w32time,stisvc.病毒释放%temp%\dll390.dll文件，设置自己为"sedebugprivilege"权限。
3.在dll218.dll中比较是否为svchost，如果不是则释放驱动文件%systemroot%\system32\nskhelper2.sys，创建名为nsdlrk250的服务，新建注册表将自身作为服务通注入到svchost.exe中运行。与驱动交互，发送控制码，恢复ssdt，遍历查找"360safe.exe"、"360tray.exe"、"avp.exe"、"ackwin32.exe"、 "anti.exe" "anti-trojan.exe"、"antivir.exe"、"atrack.exe" 、"atrack.exe"、"ave32.exe"、"autodown.exe" 、
"avconsol.exe"、 "avgctrl.exe""cfiadmin.exe"并结束等进程，删除安全软件相关文件，最后删除驱动文件。
4.创建大量安全软件的映像劫持，查找兵刃窗口，如果找到就发送消息使其退出，连接网络，下载病毒列表，根据列表下载病毒到本地运行。
5.遍历磁盘，查找移动硬盘，释放 “autorun.inf”和“system.dll”并设置为系统隐藏，利用自动播放功能运行病毒。
6.修改host文件屏蔽部分网站。
7.释放%temp%\3980500.bat文件，删除病毒文件及自身%temp%\3980500.bat文件。
