For the startup of viruses and Trojans, in addition to displaying and modifying the registry, there is also a way to make the trojan or virus into a Windows service, but this is a bad thing about its versatility, because the service uses winapi, such viruses and Trojans can only run on Windows systems, and the volume of Trojan viruses increases.Next, we need to convert the existing Trojan program into a Windows service. This requires three steps:1. Create a new main entry point and register it i

Sometimes, we need to write the program without the user login, as long as the Windows system started running, then we can write our program as a Windows service.
Services can be used by a variety of users, including local and remote users, with the ability to administer at a user's authorization level, and whether the user is physically connected to the computer running the application.
Next, I'll use a simple example to illustrate how to write a Windows service program in ATL.
