Macs CAN get viruses, but it's just much less common because virus programmers are less familiar with Apple's code and the code is not as accessible to them. But you should get a security suite to protect yourself from any viruses. I use Norton, personally.

Your Mac is no different from any other PC running Windows. You should probably protect yourself by installing Windows antivirus software. If you aren't willing to pay for any protection, there is Avast! available to download and I'd say it's the best free antivirus software out there.
