That's probably a good idea. Also, place it behind an actual firewall or properly secured *nix box just to be safe.
I had a HOSTS file used to block sites. But it got so big (479K) that my machine was bogging down processing it, I renamed it.
Nuthin but problems and popups since. Arrghhh!!!
Guess I gotta get around to installing a firewall.
Also, everybody oughta look out, there’s a nasty virus running around that spreads using messenger service.
