Both computers in our little makeshift studio are daily used for online gaming and web surfing.
It's not PLAYING games online that's the problem, it's downloading free games from dubious sources. That and NOT reading the EULA when installing.
Lots of shareware games and such can be found from reputable sites, and with shareware it's always best to check the EULA thoroughly. Quite often they will also install other software you never know about unless you read it closely.
File sharing programs are a HUGE problem...At one time every music downloading program you can think of installed spyware. Kazaa, Limewire, Bearshare, and so forth. Every one of them...and even if you manage to clean all that out, every time you go look for music, games or whatever you're connecting through a network to someone else's computer. If their computer has a virus or trojan they don't know about, guess what...YOU now have it too. And these days the first thing most malicious software does is shut down the anti virus.
That's the thing people don't understand about that type of software. When you look through the files someone else is sharing, you're actually connecting, through a network, directly to their hard drive. All it takes is opening the wrong folder...or in many cases just connecting to the computer itself, since many of these malicious programs actively look for network connections and that's all it takes. Connect and you're pegged.
Mac - Good option, from what I've heard also more expensive and software support is not as comprehensive. Same for Linux, and I like Linux really well, I just wish it were more user friendly and had better software support. Then again I haven't tried any of the newer versions of Linux in several years. You can also get Live CD versions, pop in the CD, reboot and it boots into Linux without installing anything. Shut down, remove the CD and you're back into Windows, untouched. Great way to try out Linux and see if you like it without actually installing it.
Transferring to another computer - USB drives are great, but subject to the same issues as a stand alone computer. If the source computer is infected, the malware is transferred. If you have a decent anti virus don't worry about it. Anything you transfer is checked at the time it is copied, and you can use your anti virus to scan the USB drive or SD card as well. I use them constantly, even to transfer data to and from customers' machines, but I scan my USB drive before and after doing so.

If you see me running, better catch up!
