好了，实验下。
然后找个扩展名为EXE的，（我这里拿IcesWord.exe做实验），改名为123.exe。
然后运行之，嘿嘿，出现了DOS操作框，不知情的看着一闪闪的光标，肯定觉得特鬼异~^_^。。
一次简单的恶作剧就成咧……
同理，病毒等也可以利用这样的方法，把杀软、安全工具等名字再进行重定向，指向病毒路径。如果你把病毒清理掉后，重定向项没有清理的
话，由于IFEO的作用，没被损坏的程序一样运行不了！
三、映像胁持的基本原理：　 　
NT系统在试图执行一个从命令行调用的可执行文件运行请求时，先会检查运行程序是不是可执行文件，如果是的话，再检查格式的，然后就会检查是否存在。如果不存在的话，它会提示系统找不到文件或者是“指定的路径不正确等等。当然，把这些键删除后，程序就可以运行！
四，映像胁持的具体案例：
