London:- Could your children be your weak link when it comes to home security? One of mine almost was thanks to Minecraft. One of my boys wanted to install a mod for it and needed me to approve it. And as I am paranoid about what runs on our main computer, I oversaw the whole process. At first, it all looked fine. There are thousands of mods or add-ons for Minecraft that make a variety of changes to the game. Some add new blocks, others change the way it looks and some turn it into an entirely different game.–BBC
