In any case, it might be a good idea to have both on your machine to help you deal with (unfortunately too common) corrupted users preferences problems.

Well, first, I don't think that using a FireWall is necessary unless you are a business user. It certainly isn't necessary if you don't have broadband. But even then, of all the users on the dozen or so discussion lists I'm on, over several years since broadband has become commonly available, no one has ever reported that a hacker has gotten into their machine through their broadband connection.

I think that it is a good idea. You can still pick up a virus that will infect Classic. My favorite anti-viral utility for OS X is: Intego Virus Barrier X http://www.intego.com/virusbarrier/home.html Though a copy of Virex is included with a .Mac subscription, and that works just fine. >OK Randy, it's probably all in the Macintosh Bible, but a quick rundown >might be useful :-) The last edition of TMB that I wrote for was the 6th edition. They are now up to the 8th edition, and I no longer recommend TMB. There are much better books for OS X. I highly recommend Pogue's OS X - The Missing Manual. Randy B.
