未安装微点主动防御软件的手动解决办法：
1、手动删除以下文件：
%temp%\nsb15.tmp
%systemroot%system32\fonts\irret.ini
x:\gril.pif
x:\autorun.inf (x：为任意盘符)
2、手动替换一下文件：
%systemroot%\system32\dllcache\linkinfo.dll替换%systemroot%\system32\linkinfo.dll
3、病毒修改注册表：
hkey_local_machine\software\microsoft\windows\currentversion\explorer\advanced\
folder\hidden\showall\checkedvalue
键值：checkedvalue 为1
4、手动删除以下注册表值：

病毒分析
（1）病毒运行后，查找%systemroot%\system32\taskmgr.exe是否存在，如果不存在退出当前程序；
（2）病毒设置自己的属性为系统隐藏；
（3）创建名为 "gau"互斥体，只允许一个实例运行；
（4）设置自己的为"sedebugprivilege"，以提升自己的权限；
（5）释放动态库文件"%programfiles%\netmeeting\iz.dll"，并设置为隐藏属性；
（6）创建线程，枚举并关闭杀毒软件窗口。
（7）调用rundll32.exe以bob为参数加载%programfiles%\netmeeting\iz.dll "，最后删除此文件。
（8）在iz.dll中，释放驱动文件"%systemroot%\fonts\pci.sys"，创建名称为"pci"的服务，向名称为"\\.\bob"的设备发送控制码，查找并结束360tray.exe、360safe.exe、safebox.exe、krnl360svc.exe、rstray.exe、mcshield.exe等进程，并遍历磁盘删除360和卡巴斯基的安装目录，恢复ssdt。
（9）创建线程，释放动态链接库文件%\temp%\nsb15.tmp"并加载动态链接库，并提升自己的权限。
（10）下载木马列表到到本地保存为irret.ini，然后读取列表下载大量木马等未知程序，并且结束掉大部分安全软件进程和服务和窗口，删除安全软件的文件，映像劫持安全软件；
（11）创建线程，查找类名为"afxcontrolbar42s"的窗口，关闭icesword软件；
(12)查看是否存在 %systemroot%\system32\dllcache\linkinfo.dll，如果不存在复制%systemroot%\system32\linkinfo.dll为%systemroot%\system32\dllcache\linkinfo.dll，释放驱动文件best.sys，并创建服务启动驱动，修改%systemroot%\system32\linkinfo.dll文件，删除驱动文件；
（13）对avp进行映像劫持，释放驱动%systemroot%\fonts\ttqule.sys,用来结束avp进程，然后删除驱动；
（14）遍历磁盘，释放autorun.inf和gril.pif，以达到自动运行病毒的功能。
