学徒大大帮我看看行么，谢了先...

【回复“努力减肥的猪”的帖子】
进入注册表
搜索http://www.168tom.com/dy.htm
找到后全部删除

在注册表按F3可以继续查找

没有用，注册表中根本没有http://www.168tom.com/dy.htm这个东东，问题仍未解决 ！！！ 报告完毕.........

【回复“努力减肥的猪”的帖子】
我也报告一下
楼主的日志并没有问题

估计还是注册表的问题

会不会是hosts文件惹的，你到C:\WINDOWS\system32\drivers\etc里找到hosts，以文本文档打开，把里面的内容改为
127.0.0.1      localhost
建议做之前先备份hosts，再修改。
