说明：  DLL的远程注入技术是目前Win32病毒广泛使用的一种技术。使用这种技术的病毒体通常位于一个DLL中，在系统启动的时候，一个EXE程序会将这个DLL加载至某些系统进程（如Explorer.exe）中运行。这样一来，普通的进程管理器就很难发现这种病毒了，而且即使发现了也很难清除，因为只要病毒寄生的进程不终止运行，那么这个DLL就不会在内存中卸载，用户也就无法在资源管理器中删除这个DLL文件
(DLL injection technique is widely used Win32 virus a technical. Use of this technology to the virus-usually in a DLL, the system boot time. EXE program a DLL loaded to the system of certain processes (such as Explorer.exe) Win OK. As a result, general manager of the process it will be very difficult for the virus was discovered, but even if they discover is very difficult to remove. As long as the virus parasitic process operation is not terminated, then the DLL will not be in memory and unloading, users will have no way to the resource manager to remove the DLL files)
