It's a lot easier to keep your kids safe than your parents. Your parents are unlikely interested in learning new things about computers, but they need it for all kinds of important stuff, like spending money and communicating with people. Your kids don't have that issue, and don't have any important credentials to steal. However, if they're to be safe when they grow into adults, it helps to learn while they're young. I think kids should grow up using PCs and not phones/tablets. I doubt kids can grow up to be computer literate if they spend their screen time in front of smart phones instead of PCs. Here's what I would do: Put a PC with usable specs and the latest Windows in a semi-public place in the apartment. They're supposed to have some semblance of privacy but still have an adult passing by every now and then. Give them a Windows computer that's isolated from the rest of the network, and set up an unprivileged user with an adblocker. Give them access to the administrator account (or let them figure out the password as you type it in front of them), and tell them to be careful what they run on their computer, especially as admin. Sternly tell them not to plug in USB's/CD's/whatever into any other computer except that one computer which they're allowed to use. The expectation is that they'll catch some adware sooner or later, download dubious game cracks, and generally mess up their computer. This is fine, you they're supposed to be allowed to experiment in moderation. If you fix something, try to have them around watching so that they see you solve the problem. Another good option is to take the computer away for a few days because "they messed it up, and now it has to be fixed". Even better if they have friends coming over to use the computer, as kids learn a lot from each other. Over time they might try to solve problems themselves and screw up Windows, at which point you'll reinstall it and incidentally wipe all their data. Let them surf the web, as long as they stay away from porn, violent content, etc. Instruct them to stay pseudonymous, and not to tell people or websites/games who and where they really are. Tell them it's perfectly fine to lie on a login form. Tell them that there are all kinds of people on the internet, that everyone lies on the internet and that websites are competing for their attention. If something is bothering them, they can always just close the computer and talk to you about it. Most importantly, let them make mistakes and learn from them.
