为什么我的电脑重新装完系统后开了次vagaa网页后就不可以开IE了 但是可以上QQ 请问是什么原因呢？

你可以在c:\windows\system32\drivers\etc\目录下找到hosts文件，用记事本打开，将
# 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
下面的内容全部删除（只保留上面的内容）。
