hosts文件重启后恢复,急！！！！！！

你看下你是不是装有360等等修复软件

这系列软件在修复的时候会把HOST文件还原的

装有的话你优化前先备份一份

还有可能就是那台电脑装有还原软件，重启还原。

# 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
注意：实际上#的都是注释文字，起作用的就最后行。

1. 关闭所有的杀毒软件

2. 还不行的话看下路径下有没有hosts_backup文件，修改hosts_backup与hosts文件内容一致，或者删除hosts_backup文件。
   

重新下载一个host文件就可以了
