通过Trojan-Dropper.Win32.Agent分析了 BCT、BDO、AXT、BNV、AHN等变种后
以下为查杀方法：
此病毒进安全模式杀毒软件配合360 可以查杀部分的变种
另外需要360修复漏洞（可到down.45it.com下载），并且关掉系统还原。
==============手动删除方法==============
首先断网,关闭系统还原（我的电脑--属性--还原--关闭）,清空IE临时文件夹
以下有就进行,没就继续（不同变种,进程、文件都不同）
（1）先结束进程(ctrl+alt+del组合键调用任务管理器结束以下进程)：
abc.exe
novel.exe
upnpsvc.exe
internat.exe
cdnup.exe
(2) 删除病毒衍生文件（详细步骤：打开冰刃（可到down.45it.com下载）－文件－依次找到病毒文件删除即可）
