I built my PC nearly a year ago, primarily for Gaming and Digital Art. After watching someordinarygamers, it got me wondering what a virtual machine is and how I would make one. From my very limited understanding, my guess is that it’s a sort of box you can run things in like viruses that technically shouldn’t escape the box? Anyway, there’s been a few mods, a few things on github and a couple chrome extentions I’ve wanted to try but they seem kinda dodgy, in that not many (or no) people use it or have reviewed it and as I’ve just built my system I dont want to jeopardise it. I know Muta has a whole video showing you how to set one up but last time I watched it was like a week after building and I didn’t understand what he was talking about.

So just wondering if anyone can explain what it is, is it safe to run chrome extentions and github code in? And how do I set one up if so? Thanks
