Often when I click on a website from a list, for example on search results, I get an error "This Page Cannot Be Displayed"  usually ad.doublick.net or googleadservices.com.  How do I get rid of these?  It doesn't matter if I am using Internet Explorer, Mozilla or Chrome, same results.

I found some instructions to change my HOSTS file, but it will not let me save the changes.
I have looked in Manage AddOns and they are not in the list
I have looked at Control Panel Remove Program and they are not in the list

I am running Windows 8.1
