修复
删除C:\WINDOWS\svchost.exe

若删除不掉
用Unlocker工具删除试试
工具下载、使用参考http://forum.ikaka.com/topic.asp?board=28&artid=7471002

不行重启后又出现我上次要到注册表修改的

O23 - Service: Gray_Pigeon_Server (GrayPigeonServer) - Unknown owner - C:\WINDOWS\svchost.exe

修复
重启
删除C:\WINDOWS\svchost.exe

注意顺序

还是不行重启还是出现,而且在C:\WINDOWS\找不到svchost.exe只有在C:\WINDOWS\system32我没有安装杀毒只有防火墙,请问还有其他方法吗?

O23 - Service: Gray_Pigeon_Server (GrayPigeonServer) - Unknown owner - C:\WINDOWS\svchost.exe
1.开始-运行输入regedit,打开注册表编辑器，定位到HKEY_LOCAL_MACHINE\ SYSTEM \ CURRENTCONTROLSET \ SERVICES分支，删除左栏中的病毒服务名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%windows%下寻找病毒文件名C:\WINDOWS\svchost.exe,C:\WINDOWS\svchost.dll,C:\WINDOWS\svchost_Hook.dll,C:\WINDOWS\svchostkey.dll,能找到的都删除
特别注意: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。这一步

还不行难道真的没有办法

请各位救救我

用Autoruns保存一个日志发上来
日志保存方法:选择File->Save菜单项
保存日志时注意选择Options->Hide Microsoft Entries菜单项(设置了这项后点工具栏的刷新按钮)
