Why does my Windows computer without any AV software never get a virus? I dunno, maybe it's that people do dumb things. Chances are, you're gonna run into a lot of problems with Linux. You don't just run an installer, you have to do this stuff manually, with a command terminal. Linux geeks, please stop pushing something so complicated onto unsuspecting bystanders.
Really, it's not that complicated. Maybe if you stopped and thought to learn to use a powerful piece of technology instead of expecting it to do everything for you, the concept of using a terminal for all three seconds wouldn't seem that complicated.
As was already said, Ubuntu is easy pie and one of the most common distros amongst your average computer user. Secondly, you can dual boot your HD; so you can choose to boot into windows or Linux on start up. That way if something happens to your windows setp, you can recover the data off of it and re-install it. You could also consider virtualization, though I"m not sure how smoothly it will run games.
