No, they don't have viruses or any of that stuff because no major corporate company uses Macs for servers or holding important documents or files and such, so all the hackers are like "What's the point hacking Macs if no company that has stuffloads of money to steal uses Macs?" So, instead, they make malware for Windows because Windows is popular and used by major companies (Obviously, including Microsoft, hurr). That means we gotta defend for ourselves.
You guys are sitting around playing with iLife and iPhoto, we're playing games and detecting malware.
