注:停留下后，AIT+F9返回到用户代码后，查找2进制字符串FC DB E3 E8 ?? ?? ?? ??
易语言查找字符串采用ASCII码查找
注：多数易语言采用花指令对易格式体进行保护，所以在查找字符串之前尽量先去掉花指令，去花的OD插件 E JUNk CODE

VB入口特征查找函数 ThunRTMain
VB 查找字符串时采用二进制字符串816C2404??000000
注：识别VB P-code编译时，只需要查找不到按钮事件就是P-CODE编译
P-CODE代码是虚拟代码，需要独立的调试器
Vb 查找字符串采用 UNICODE码查找
DIE64类似于PEID的功能，但是他强大之处，在于他可以不管是任何壳保护的情况下，都可以识别出他的编写语言
当程序提示说有压缩代码时，就表示程序已经被压缩或者加密
VMP
看起来很凌乱，就像未解码的代码一样，VMP保护分两种方式,让代码
1.乱序
2.虚拟
VMP在默认保护的情况下是不会保护功能代码的，并且VMP保护功能代码只是一个区段，如果大家看到的.VMP区段有三条的话，就表示此程序已经被VMP进行了最大保护，如果只是一条区段的话，那就是乱序保护，两条区段的话，就是乱序加虚拟保护
