Filename: LMHOSTS
WWW.GOOGLE.COM 127.0.0.1
The LMHOSTS file is a file used by most implementations of TCP/IP protocol in the Windows and Linux and Unix world.
It overrides the standard DNS (Domain Name Service) resolution protocol and re-directs a named domain query to the address specified. 127.0.0.1 is YOUR computer.
That line added to your LMHOSTS file would prevent your computer from ever being able to get to Google again.
