It's a rarity to find Mac malware, let alone for it to infect OS X. Exact opposite for Windows. Apple just puts out an OS X update, malware gone. The manual removal instructions for Macs are as simple as can be. Microsoft puts out Microsoft Security Essentials, which doesn't work for tons of malware. its really just Windows dressing. Microsofts MRT (Malicious Software Removal Tool) which gets ran with most Microsoft updates doesn't catch most malware. So your Windows PC gets updated while malware is still present. Your system restore points contain the malware. There is an art to getting rid of malware on Windows. If you go to Geek Squad they'll remove it for $100-200. Geek Squad also teaches computer courses. Is there a course in how to get rid of malware? No, they explicitly state that they will not teach somone how to get rid of malware. It's a racket that the anti-virus purveyors want to bring over to Android and Mac while whole platforms are moving to closed models that do no one any good except for the company. Macs will soon be able to only download apps from the Mac store (Mountain Lion will have option to download from anywhere, but after that?), Windows PCs will only be able to download apps from the Windows Store (Windows 8 on ARM), and Android machines will only be able to download apps from Google Play (No more sideloading, no more Amazon App Store, etc, you'll be forced to root). Linux will have its day. It will be the only open platform with privacy and security built-in. Any malware that penetrates will be easily removed as there are thousands of Linux people monitoring these things. Security scares always benefit someone besides the user; whether that is malware writers, anti-malware purveyors, or even fascist government like the US government is becoming in calling for real-name identified users of the internet. Companies will follow the US govt which is why you're seeing things becoming closed. Apple knows exactly who you are on your iPod, iPhone, or iPad because of Apple ID and if you ever purchased anything from them. Android and Google want real info anyway they can. Windows 8 is a big leap toward big brother. I'll be moving to Linux full-time when this all goes down.
