Open the hosts file and see if there are any errand entries in it. Copy the original to the desktop and add .txt to the end of the file so you can open it up in Notepad.
File location (I think from XP to 7 it's all the same location):
Here is what the stock hosts file is supposed to look like.
Code: Select all
# 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
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 22.214.171.124 rhino.acme.com # source server
# 126.96.36.199 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
Have you tried ipconfig /release, then ipconfig /flushdns, and ipconfig /renew? Maybe go as far as trying the connection straight out of your modem bypassing any router/switch?
To keep this guy/gal from getting more spyware/viruses use this software (the Hoftile link) to block the bad addresses at the hosts file. If the hosts file blocks the IP/address then it won't be able to do anything. Spybot Search and Destroy does this with the Immunization feature. The very last thing it applies the immunization to is the computer's hosts file. I uploaded my hosts file list and a very useful app called AdBin. Open up AdBin, Import List (my list), click Block, then Lock. Once you've done that make sure you tell it to Save otherwise it won't stick.

It's a Hotfile link but I have it setup so you shouldn't have to wait. Let me know if you do.
After you get the computer setup I recommend you install Avira Free edition. The program is overly protective, why I don't like it, but for other people's machine's it's all I use. The problem with Avira Free is after every update there is a giant ad on the screen. Luckily there's a simple program to disable that too.
