病毒分析
1.病毒运行后检测自身是否被调试，如果是，则遍历查找ollydbg.exe，ollyice.exe，c32am.exe，peditor.exe，importrec.exe，loadpe.exe等进程并将其结束。
2.病毒释放%temp%\dll218.dll文件，设置自己为"sedebugprivilege"权限。
3.在dll218.dll中比较是否为svchost，如果是则释放驱动文件%systemroot%\system32\nskhelper2.sys，创建名为nsdlrk250的服务，通过向设备"\\.\nsdlrk250"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.比较是否为%systemroot%\system32\svchost.exe，如果是就执行explorer.exe。
5.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。
6.开启anmanserver和browser服务，以命令行的方式删除temp%content.ie5\down*.exe，每隔3秒反复执行此动作。
7.遍历磁盘，在每个磁盘释放 "autorun.inf"并设置为系统隐藏。
8.在dll218.dll中释放system.dll，并在"autorun.inf"中设置用rundll32.exe以explore为参数启动system.dll，访问网络。
9.修改%systemroot%\system32\drivers\etc\hosts。
10.释放%temp%\3980500.bat文件，删除病毒文件及自身%temp%\3980500.bat文件。
病毒创建文件：
%temp%\dll218.dll
%temp%\3980500.bat
