宝马x7二手车价格:网页登陆

这个你到工具－－internet选项－－常规－－主页里面把它改为空白页就行了，
如果在这里改不了，那就说明你的ie被恶意胁持了，最好通过一些专门的软件，比如说“卡卡助手”之类的来恢复系统。

我建议你看一下这个地方
C：\windows\system32\hosts
这个文件，用记事本打开，如果不是下面的这样，就改成这样
# 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
