127.0.0.1是本机IP地址,不知道你的什么程序自动访问该地址(现在有些病毒为了防止用户访问反病毒网站了解安全知识会在hosts文件中指向127.0.0.1就会导致系统自动访问127.0.0.1导致无法打开网页。你可以搜索“hosts”(不含引号)文件找到以后用记事本打开然后清空里面的内容就可以了(也可以直接删除)。
1.dns问题
2.在系统盘下搜索hosts文件,用记事本打开。看内容是不是和我的一样:
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
肯定是中了病毒或木马或者IE被修改,没有他们说的那么麻烦,先用最新的杀毒杀一下,然后用上网助手修复IE
你看看IE-->工具-->internet 选项-->连接-->局域网设置.看看代理服务器设置的是否正确
