我打开 www.pconline.com.cn的时候，主页会自动跳到www.50365.com。一个手机注册的收费电影站点，其他的网站和连接均正常。
请问，是什么问题，怎么解决？

修复(fix checked)上面的项目，重新启动到安全模式，在文件夹选项中，显示隐藏文件和取消“隐藏受保护的操作系统文件”。然后找到如下文件并删除（如果有的话）。
C:\WINDOWS\System32\BoCaiToolbar.dll

用记事本打开hosts文件看看.

在win 2000/xp是: C:\Windows\system32\drivers\etc\hosts

HOSTS文件里保存有WINDOWS系统记录的IP地址与域名的对应关系。

有些网页恶意代码会修改这个文件迫使我们访问恶意网页/网站。
