First, I'm a complete beginner, my only experience in malware is running windows defender lol. But I will try my best to learn anything that you guys recommend.
My younger brother keeps downloading games from shady websites, thankfully till now he hasn't gotten a virus from any of them. I wanted to teach him why it's unsafe to do this by doing the same, but on a virtual machine and showing him how they can be infected with malware, and also why malware is bad. I was thinking of just using VirtualBox, but if any of you have any other suggestions then I can look into more options as well!
So, how can I show him that the game I downloaded on the virtual machine came with malware?
Also, this is just paranoid me talking, but I saw somewhere that viruses can infect main systems even if i run them on virtual box? I'll be doing this on my main laptop so i really cannot risk getting a virus on it, so just wanted to confirm.
