*waves the magic wand* Everyone needs to calm down here. There's too much bickering and not enough positive discussion. For what it's worth, my standpoint is that an OS is only as secure as the user behind it. Everyone has mentioned running Windows with AntiVirusX and FirewallY, but I've got neither, and it's been that way for several months now. Have I got infected? Nope. I've actually got three computers of mine running like this. It's tried and tested proof that you don't need security software. I don't recommend that others do the same, but if your wife is infecting the computer dispite security software, then it's simply a problem of her computing practices.
