症状：今天开机后会不管运行IE与否，会不定时地（大概每三分钟)打开一个IE窗口指向广告网站

操作系统:win2k cn sp4，经windows 网站更新过最新补丁
已装norton 7.6 ce 版更新至最新病毒库

已尝试的方法：
1，控制面板删除部分可疑软件。
2，手工删除可疑的c:\winnt, c:\winnt\system32, c:\program files, c:下的可疑的修改时间为今天的exe文件，部分无法删除的重启进入安全模式删除。
3，用超级兔子，无效果。
4，用Spybot - Search & Destroy软件删除了所能扫描到的东西(除windows security center的东西外)，部分无法删除的也进入安全模式下删除。主要有两个名字分别为command和network monitor的软件。
5，用cwshedder扫描无发现任何问题。
6，用hijackthis 运行后log 如下，尝试修复部分但依然无效果。
