Many Spyware/Adware programs block access to the hosts file. So there is a big chance you may fail doing it this way. Imho it would be better to block the URL in the firewall

The 'hosts' file maps IP addresses to hostnames, so it doesn't need the protocol bits and pieces.

You should be aiming to write "127.0.0.1 hostname" to the file, e.g. to block 'badsite.com' you'd add:

127.0.0.1 badsite.com
127.0.0.1 www.badsite.com

There are probably better ways to block a site though ;-)

First, this is not an effective method to block websites, but if you really want to do it this way, then look up the format of the hosts file.

If you want to block a website by essentially hijacking the DNS lookup, you need to redirect the hostname only.

The hosts file you are generating looks something like this:

127.0.0.1 http://website/file

What you want to see in the file is this:

127.0.0.1 website
