在这里首先先感谢飞跃迷离提供的详细帮忙,
通过你的指点,我按步就班,终于解决掉了那些讨厌的网页(注:我刚开始用了3721雅虎助手等
都没有办法解决)真是热泪盈眶啊,再次感谢飞跃迷离.

不过还有一点小问题还需要飞跃迷离解决.
就是我用傲游浏览器时,主页明明为空,但登陆时就跳出http://www.9991.com/这个网页
另外,我自己设了其它主页,问题一样还是跳出http://www.9991.com/这个网页
而用IE却没有这个问题.
还有就是用傲游浏览器时经常出现当前页面的脚本发生错误.

希望飞跃迷离能够提供详细的解决办法.多谢了.

请再扫一个log贴上来

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。）

开始→控制面板→性能和维护→管理工具→服务→查找Local Network Service、Net Boot Service→右击→属性→启动类型→禁止→应用→停止→确定。

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\SeedServ.exe
C:\WINDOWS\system32\big5_gb2312.exe

问题仍在请把您的遨游浏览器卸载后重新安装...

打开IE浏览器--工具--internet选项--高级--在“禁止脚本调试”前打勾


big5_gb2312.exe（C:\WINDOWS\system32），麻烦您将这个文件压缩加密后发给我看看。

如果压缩加密，请参考：

呀~！可是雅虎助手对于什么都不懂的人还是有点用的吧？能解决不少问题呢！
