HOST文件被恶意篡改怎么办

1、HOSTS文件位置在“c:\windows\system32\drivers\etc“
2、将hosts文件复制到桌面，用记事本打开，删除记事本的全部内容，将以下内容复制后放入文件然后保存：

# Copyright (c) 1993-2009 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
# localhost name resolution is handled within DNS itself.# 127.0.0.1 localhost# ::1 localhost
