Bit of a wakeup call, to regularly check your logs on your home router and/or firewall - simply look at some of the outbound IP addresses accessed (especially if you can see from which machine they originate).

Also, I'd say just don't let any old machine use browsers/the Internet (even your phone); just those that you've got good parental control on, good oversight of, and that aren't hidden away in your child's room.
