Viking的肆虐让很多受害者忍无可忍，更可气的是专业软件公司提供的专杀工具竟然无法彻底清除。
无奈之余自己动手写了一个，请需要的朋友到这里下载：http://www.chenoe.com
该工具可以有效解除被感染的exe中的病毒并还原exe文件，网上的大部分工具是直接删除exe文件。另外，本工具还具有Viking免疫功能。
下载后直接运行即可查杀，如果查杀几次都有无法关闭的进程的，重新启动一下计算机继续查杀应该可以杀掉。直到病毒数为0时为止。
另外提供该工具中结束进程部分的代码，结束进程一般采用TerminateProcess函数，但是对于比较顽固的进程就要用非常规的手段来Kill了。
我的方法是，先提高本程序为Debug级别的权限。再用TerminateProcess关闭，如果失败就枚举该进程中的线程并用TerminateThread关闭。然后再用TerminateProcess结束进程。这样就基本上可以关闭99％的非系统进程了。
还有，对于被注入了病毒dll的进程，要先枚举进程中的模块并判断。然后决定是否Kill，Kill方法同上。
以下为进程、线程、模块相关的代码：
