先谢谢各位了

O23 - Service: Event Log Management Service - Unknown owner - C:\WINDOWS\svchost.exe
O23 - Service: windowsServer - Unknown owner - C:\WINDOWS\windws.exe (file missing)
这两个是（后面一项文件已经没了）。参考http://forum.ikaka.com/topic.asp?board=28&artid=7713905处理。

进入控制面版的添加删除程序中卸载Winstdup
开始→运行→services.msc→确定→查找windowsServer，SDAgent Service，Event Log Management Service→双击→启动类型→禁止→停止→应用→确定。禁止windowsServer，SDAgent Service，Event Log Management Service这3个服务。
关闭所有浏览窗口以及一些不必要的程序
运行Hijackthis，扫描结束后在下列选项前打上勾，然后选"修复""

双击我的电脑--工具---文件夹选项--查看选项卡--单击选取"显示隐藏文件或文件夹"清除"隐藏受保护的操作系统文件（推荐）"复选框。在提示您确定更改时，单击“是”
(请按上述步骤操作，不要略过)
然后找到如下文件并删除（如果有的话）
C:\WINDOWS\windws.exe
C:\Program Files\Common Files\smartde
C:\WINDOWS\svchost.exe
C:\WINDOWS\SYSTEM32\stdup.dll
C:\WINDOWS\system32\obwbkya.dll
C:\PROGRA~1\COMMON~1\Wnwb\wnwbio.dll
以上文件如果删除不了，请重启后再删除。
