我电脑应该有病毒。但是重装了系统还是有病毒。有个网页一直是主页。改不了。为什么。杀毒软件也没用http://www.4199.com。就是这个网页。一直都是主页。请各位高手帮忙解决。谢谢
还有系统应该怎么重装。到后面有几个选择应该选哪个。有保持现有系统。用。。。格式化分区啊。什么的。我不明白。我都是选保持原来系统。

首先找到hosts表，hosts 表的位置：C:\WINNT\system32\drivers\etc ，用记事本打开依次将文件打开（一定用记事本打开），可以看到的以下为正常，如果被改到 125.91.1.20 那就是中了4199了。只要是hosts表里的文件连接到这个IP的都删除(125.91.1.20)！

# 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

其次是查找users.dll 文件
