看到这里，你应该会问：那么要如何为装？下面我们简单的介绍一下：
1、用ToPo增加大约128字节的空间[注:个人爱好而定],
2、进入LordPE的PE Editor,打开Target.exe,
把.topo0段名改为.text,装的更像一点[注:也可以个性一点改成自己的大名,不影响结果]
记下VOffset:13000,把入口点改为这个值.OllyDbg载入Target.exe,轰~我们来到了一个异常,
向上拉动滚动条,来到413000处改写代码:

mov eax,fs:
push eax
mov fs:,esp
＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋下边再恢复 ＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋

mov fs:,eax
pop eax
pop eax
pop eax
pop eax
mov ebp,eax
＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋＋
别忘了jmp 405000,也就是壳的入口点.选中修改过的代码按右键,把它保存为newTarget.exe.
PEiD侦测一下:Microsoft Visual C++,并且运行正常,任务完成
以上的可以再入口点前面加上代码来迷惑杀毒软件，或是想破解自己辛苦编译出来的软件！！！！
其实做免杀比较好的论坛还是比较推荐 甲壳虫
