This file can be cleaned, but it must be done very carefully. If you are on a computer network, ask your network administrator for help, as removing the wrong entry can deny you access to some resources
To find your Hosts file, named “HOSTS”:
Windows XP:
* Access folder C:WINDOWSSYSTEM32DRIVERSETC in Explorer.
Windows 2000:
* Access folder C:WINNTSYSTEM32DRIVERSETC in Explorer.
Windows 95/98:
* Access folder C:WINDOWS in Explorer.
Open file “HOSTS” in Notepad. Before making changes, do a “Save As” and save a backup of this file as “HOSTS.BAK”. Then reopen the HOSTS file.
Now, delete all entries in this file except for the following and any other entries you are sure have legitimate uses:
127.0.0.1 localhost
Resave the file.
