Back again with another problem.
All of a sudden a new search bar has appeared on my web browser named Bing.
I searched the net and apparently a lot of people have had this problem and there are various way's to cure it.
Tried quite a few with no success, the latest one involves adding two extra line of text to Hosts in the Windows/System 32 file, then saving it using Notepad.
First I made a backup of Hosts.
Then when I try this and get to the Save part I receive this message:
You dont have permission to save in this location.
Contact the Administrator to obtain it.

I have had this message before and I am the Administator (I think)
I am the only person using the computer, which is the main computer on a network of two computer's.
When I go into the control panel>User Accounts my name is displayed underneath of which is the words Aministrator Password protected.

I would appreciate help on solving this Administrator problem.

Thanks
