I just read their entire web page. This program looks perfect for me, assuming that it will work with the soon to be released Leopard OS. Here is the one I am looking at:

Internet Security Barrier X4 Antispam Edition - Single-user license


Is this the one you would recommend from their list of offerings? LINK

Last but not least, will the MacBook have it's own robust firewall, so I won't need to buy an aftermarket firewall. My assumption is that I won't need to buy one.

I'm just trying to get all my ducks in a row prior to purchase.

Thanks!
