删除（如果有的话）
c:default.mht

另外您的防火墙开的有点多了，天网、东方杀毒、金山毒霸、上网助手……建议关闭两个试试

请问该如何删除
c:default.mht
我的天网防火墙早就卸载了,怎么还会有呢?

显示隐藏文件

双击我的电脑--工具---文件夹选项--查看选项卡--单击选取"显示隐藏文件或文件夹"--清除"隐藏受保护的操作系统文件（推荐）"复选框。在提示您确定更改时，单击“是”--单击“确定”。

然后找到如下文件并删除（如果有的话）。

default.mht（请用开始菜单中的搜索功能查找）

如果您的天网已被卸载，请修复

【回复“魔法学徒”的帖子请问该如何删除
c:default.mht
我的天网防火墙早就卸载了,怎么还会有呢?

【回复“魔法学徒”的帖子】已经照你说的做了,但还是不行.没有找到default.mht这个文件,已经修复04 skynet,请问是否要进入安全模式下修复?

【回复“007黄金眼”的帖子】
楼主找一下有没有C:\WINDOWS\SYSTEM32\IEXPLORE.EXE这个文件。
