网上也看了 很多帖子 我晕啊！！
C语言支持 直接 汇编 而E语言却要 转换成10进制 饿 处理相当麻烦
这个事我开学时候写的驱动：360玩的太绝 一直更新偶的驱动 麻麻呼呼 还有很多没有解决 感兴趣的朋友玩玩吧！ 吧里面的功能全部挖出来 [ATTACH][ATTACH][ATTACH 不过360急救箱确实有一个问题 如果第一次加载失败了 第二次即使被成功加载
进程也不会得到保护
NtLoadDriver 请在虚拟机中测试 这个NtLoadDriver 我只写了HOOK 请手动恢复 自备XueTr 先让360急救箱允许 在结束 恢复 NtLoadDriver 在运行看看 360失去了 进程隐藏+进程保护 即使驱动被加载 [ATTACH] viphack.zip
