怎样彻底杀掉？

O23 - Service: Gray_Pigeon_Server (GrayPigeonServer) - Unknown owner - C:\WINNT\G_Server.exe
1.开始-运行输入regedit,定位到HKEY_LOCAL_MACHINE\ SYSTEM \ CURRENTCONTROLSET \ SERVICES分支，删除左栏中的病毒服务名Gray_Pigeon_Server (GrayPigeonServer)
2.重启系统，在“文件夹选项”的“查看”面板中勾选“显示系统文件”、“显示所有的文件和文件夹”两项，点击“确定”按钮。然后在WINNT下寻找病毒文件名G_Server.exe,G_Server.dll,G_Server_Hook.dll,G_Serverkey.dll能找到都删除
还有建议修复O23 - Service: RavTime - Unknown owner - C:\WINNT\win_sys.exe (file missing)
修复这项前要在控制面版-管理工具-服务里把RavTime关闭并禁用,然后才能修复

还有建议修复O23 - Service: RavTime - Unknown owner - C:\WINNT\win_sys.exe (file missing)
请问这一项怎样修复呀

在HijackThis扫描好的界面上， 看图
