I would like to point out that it is a possible security risk to install an /etc/hosts file that you download from somewhere unless you are careful to look at the contents of that file to be sure that it is only doing what it advertises.

Excellent point! But you can use the shell to easily confirm that no rogue entries exist in /etc/hosts.

The following shell command will display any lines in /etc/hosts which do not start with sites which point to either 127.0.0.1, 0.0.0.0 or start with a comment.

grep -v "^127.0.0.1|^0.0.0.0|^#.*" /etc/hosts | more

If any lines are output, you can easily check to see if they are valid or rogue entries.

This worked for me:

grep -v -e "^127.0.0.1" -e "^0.0.0.0" -e "^#" -e "^\s*$"
