If you change any of the crap below remember after you save that file go to start run then CMD
type the following
ipconfig /release
(hit enter)
ipconfig /flushdns
(hit enter)
ipconfig /renew
(Hit enter)
then restart
enable hidden folders and look for C:\windows\system32\driver\etc then open the Host file with note pad
these are the only things that should be in there, you can do redirection in there so if some one types in Google it goes to yahoo and yahoo goes to Google its pretty awesome.
