应该怎么做啊?感激!!

重新启动到安全模式（进入安全模式的方法:重新启动电脑, 开机自动检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式(Safe Mode)进入Windows。）

先终止下面的进程（关闭所有窗口，同时按下CTRL+ALT+DELETE，在打开的窗口中选中要终止的进程，然后按下“结束任务”或者“结束进程”，最后关闭该窗口。
C:\WINDOWS\system32\dmad.exe

请关闭所有IE界面，重新使用HijackThis扫描一次，选中下面建议修复的项目，让HijackThis修复，修复前请允许HijackThis保留备份。（如果楼主知道是安全的可以不必勾选）
O4 - HKLM\..\Run: [SEDMAD] C:\WINDOWS\system32\dmad.exe "-sedmreg"

然后打开我的电脑→再点工具→打开文件夹选项→查看→把隐藏受保护的系统文件（推荐）和隐藏已知文件类型的扩展名的勾去掉→再显示所有文件→找到以下文件并删除：(如果有的话)
C:\WINDOWS\system32\dmad.exe

O4 - HKLM\..\Run: [SeAdUpdate] C:\WINDOWS\SeAd\SeAdUpdate438d4756.exe
上面两项如果不是楼主安装的，建议修复并删除相关文件…

谢谢各位,终于弄好了,多亏了上楼的高手帮忙!!
我把  O4 - HKLM\..\Run: [SeAdUpdate] C:\WINDOWS\SeAd\SeAdUpdate438d4756.exe给删了就没广告了! 呵呵!
谢谢各位,感激涕零!!
