先说一下NT服务的特点：
1.随系统的启动而启动
2.隐蔽性比较好，一般的手动方式不能删除
3.只适用于NT内核的OS
WIN98下的请参考RegisterServiceProcess API,这个API函数将进程注册为一个服务模式的进程.
下面是我写好的class,你只要在这个程序中用这个包含这个.h文件就可以了。
======================

if (svc!=NULL)
{
StartService(svc,0,NULL);
CloseServiceHandle(svc);
}
CloseServiceHandle(scm);
}
好了，这个服务程序到此就结束了，写个测试程序吧，然后用
CService ntservice;
ntservice.Init_Service_Table_Entry();
到你的控制面板，可以看到系统的服务中是否多了一个virusservice
本程序在winxp+vc6下测通过。
