If you don't trust them alone on your machines, set a password in your bios and be done with it.

It's sensible to have AV, software firewall, and a router with up to date firmware and firewall activated.

Also prevention, Spyware Blaster and Spybot S/D immunizer are good free tools to download and use. There are many more, I prefer those two.

Have never owned a Norton product so can't comment on that, but the mere mention sure stirred up a bee's nest.

Besides that, I agree with and will not repeat previous Admin account debacle other than create a user account for your guests.
