The short answer is "yes", but the truth is a bit more complicated.
When you run Windows on Mac OS X, there's a layer in-between called a "virtual machine". Parallels is one popular virtual machine. VMWare is another. The Windows copy, and the Windows applications you run on it, are open to the same vulnerabilities that they would be if you ran them on a "real" machine (like a desktop PC).
If you connect your "virtual machine" to the internet without a firewall, your virtual machine could be affected by malicious code. It won't directly affect your Mac, but it could use up resources that your Mac applications also use. For example, some malware might use network bandwith by sending spam constantly. While your virtual machine is running that malware, it will also be using network bandwidth. Shutting down the virtual machine will (temporarily) stop it.
Kick the virus... use a petrol burn it, so you can reinstall your windows again.
Windows computers are the target of almost every computer virus on the planet because Windows is the most popular type of OS (Operating System). Think about it, if almost 94% of the population who have computers on Earth are using Windows, don't you think hackers and virus writers will take advantage of that and aim at every Windows computer? Apple computers and like you stated, Unix computers, are less vulnerable to virus attacks because the majority of computers are Windows (that's not to say you still can't get a virus if you have Apple or Unix).
Yes, a mac can if its running windows, but only the windows operating system will get it not the apple software itself>
Windows software generally should not have viruses - BUT - weaknesses in the OS are exploited by virus authors to attack computers running Windows OS.

Windows servers are not necessarily failure-prone moreso than say Linux or Mac servers. However, Windows servers do suffer more frequently from hacking and virus attacks.

Viruses attack weak points in the Windows operating system and so they do not affect the Mac's operating system. If you are running Windows on your Mac then you will need to ensure that your Windows installation is protected.
