how risky is it to have Macs online these days?

He was Windows before he met me then Macs took over his life. He still believes that there are latent programs, even with Macs, and especially with Intel Macs... but I've shown him your posts already and he's starting to make concessions.

When you say behind a router, do you mean as part of the network that goes through our existing wireless router?

Thanks!
