I would advise you to get a Mac. If you can't afford a new one you can buy a nicer used one online for half the price. Windows XP is very vulnerable to viruses and doesn't work very well. I know vista, 7, and 8 don't work much better.
Macs are vulnerable to malware too. Really, the best way to avoid malware infections, is to run a decent AV, have some security addons (like Noscript, AdBlock Plus, etc.) installed in your browser, and use common sense when it comes to installing programs. Whatever you do, if you download a freeware program, turn down ALL the offers it gives you involving other programs, and don't allow it to install any toolbars.
Running Linux is not a bad idea either, as it is inherently more resistant to malware than Windows or Mac OS. Mac OS used to be more secure because hardly anyone used it, but now as it's achieving more popularity, more malware is being developed for it, and a lot of it just happens to be extremely difficult to remove. On Linux, you pretty much need to type in your password any time you install a program or make any other system-wide changes, and when you're doing just normal day-to-day tasks, you never run as a superuser/administrator, so that makes developing malware for Linux nearly pointless. Now, contrary to popular belief, malware does exist for Linux, but it is extremely rare, and it mainly targets servers rather than normal home-use systems. If you're not hosting a website or doing anything else of the sort on your machine, you should be fine.
