病毒分析
1.遍历进程如果发现360rp.exe和360sd.exe，就调用命令行删除360rp服务，结束360rp.exe和360sd.exe进程。
2.检查"%systemroot%\system32\at.exe"是否存在，如果不存在就退出当前进程。
3.释放并执行病毒文件"%program files%\spoov.exe，然后退出当前进程，调用命令行自我删除。
4.在spoov.exe中，检查"%systemroot%\system32\cmd.exe"是否存在，不存在就退出进程。
5.查找病毒当前目录中是否存在autorun.inf，如果存在，就执行explorer.exe。
6.如果不存在就创建名称为"fbsrs"的互斥量，提升自己为"sedebugprivilege"权限。
7.创建线程，枚举窗口，遍历进程，如果发现avp.exe、360sd.exe、rstray.exe、ravmond.exe等进程，就关闭这些进程创建的窗口；如果存在kswebshield.exe、kav32.exe、kpfw32.exe、vptray.exe、mctray.exer、tvscan.exe、vpc32.exe、mcshiled.exe进程，就通过释放其内存使这些进程退出；如果发现ekrn.exe，就删除ekrn服务，结束ekrn.exe和egui.exe进程；如果发现nod32krn.exe，就删除nod32krn服务，结束nod32krn.exe和nod32kui.exe进程。
8.释放并加载动态库文件"%systemdriver%\lzl.dll"，并设置为系统、隐藏属性。
9.在lzl.dll中，释放驱动文件"%systemdriver%\windows\fonts\pci.sys"，创建名称为"aae"的服务，恢复ssdt，遍历查找并结束
10.360safe.exe、360tray.exe、safeboxtray.exe、360safebox.exe、krnl360svc.exe、zhudongfangyu.exe、rstray.exe、360sd.exe、360rp.exe、kavstart.exe、kswebshield.exe、mcshield.exe等进程，删除安全软件相关文件，最后删除驱动文件。
11.创建线程，释放并加载动态库文件dll1.tmp，在dll1.tmp中，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。
12.创建线程，遍历查找avp.exe，找到后通过卸载avp进程模块，使进程退出，停止avp相关服务。
13.删除动态库文件lzl.dll。
14.检查"%systemdriver%\system32\dllcache\linkinfo.dll"是否存在，不存在就拷贝"%systemdriver%\system32\linkinfo.dll"到此文件夹，释放驱动文件"%systemdriver%\fonts\nnix.sys"，创建名称为"nnix"的服务，感染"%systemdriver%\system32\linkinfo.dll"。
15.遍历磁盘，在每个磁盘下创建autorun.inf和haz.pif。
病毒创建文件：
%systemdriver%\fonts\nnix.sys
%systemdriver%\fonts\cdh.ini
%systemdriver%\fonts\pci.sys
%systemdriver%\lzl.dll
%temp%\dll2.tmp
x:\ haz.pif
x:\ autorun.inf
x移动介质。
