Hi.

By default, Windows 7 has done away with the hosts file. A sample might be present but all the lines in it will be commented out. This is to help in the transition from Internet Protocol version 4 to Internet Protocol version 6. So the default settings for the localhost are now handled internally by the DNS subsystem so a hosts file is no longer needed. The only time you will find one is if it has been created manually (or possibly malware has created a corrupted/compromised one and or edited the sample etc).
So if you so wished you could use the below application to install either the HPHosts or MVPs Hosts.
Host File Reset/Replace:Please Download
HostsXpert and unzip it to your computer, somewhere where you can find it.
The root of the system drive would be a ideal location EG:
C:\- Right-click on HostsXpert.exe and select Run as Administrator to launch the programme.
- Check to see if top button on left hand side says Make Writable?
- If it does. click on it then proceed to next instruction.
- If not, just proceed to next instruction
- Click on Restore MS Hosts File to restore your Hosts file to its default condition
- When prompted to confirm, click OK.
- Click on the Download button (lower left hand side)
- Click on MVPs Hosts... button.
- Click on Replace button.
- Press OK in the box that pops up. (HostsXpert will now download and update your Hosts file)
- When finished.
- Click on File Handling button.
- Click on Make Read Only? to secure it against infection.
- Exit the programme.
