Hello, my name is Troy, I'm a Mac and I'm completely clueless about PC security. Okay, not totally. I'm running Win 7 in Bootcamp and have anti-virus software running but that isn't my question.

I'm going to build a gaming PC primarily for SC and a couple of other sims and will only be playing games on it. I want to lock the thing down as tightly as I can and still have the games function. What would be the best way to go about this? A link to a decent article would do as well as anything. :)
