apparently does its filtering through the HOSTS file you should be able to browse to it with Windows Explorer at C:\Windows\system32\drivers\ect\hosts then make sure it is not set to read only in its properties then open the HOSTS file in NotePad (or any other TEXT EDITOR) and delete the lines containing the URLs you listed. Next, save the file and close NotePad.
I recently installed focal filter and blocked a few sites for 2 hours (last night). Nothing got blocked since my browser was open the entire time(until this evening, when I had to restart my computer.) Uninstalled and removed all my blocked sites from the list, then focal filter came up with an error message stating.
Focal Filter was unable to change your system settings.
Access to C:\Windows\system32\drivers\ect\hosts is denied.
Basically I need to know how to get access to this (Figured out the advance command prompt and entered this in and what not) I just don't know what to put in so I can get access to facebook back.
Chrome also gives me this error message
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
Thanks for the help.
