你好，我也是遇到打开特定网页跳转到垃圾网页，按你之前给别人的回答去做，搞不大清楚，希望你能帮忙

浏览器被劫持有时候还是很麻烦的，我用QQ浏览器，经常打开就跳转到某网页，但是重装软件后又好了。现在也没用QQ的了。
360一般不会，遇到过一次，用360扫描杀毒一次就解决了。
IE也容易出现这种情况，用更改主页的方式即使改好了，也会加载主页的瞬间跳转到某个网页去。
路径：c:\windows\system32\drivers\etc进去后，找到hosts这个文件，右键用记事本打开。然后清空里面所有内容，再粘贴以下内容：

# 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

保存后，重启电脑。

装一个360修复一下浏览器
