I have been checking the forums and if there are 600,000 infected Macs out there, they certainly aren't admitting it. I am not seeing it. Nor are the other security companies finding them. Only Doctor Web is claiming it. . . And that company is suspect. We've seen this kind of hype before. They have an anti-virus product to sell. . . One that is specifically designed to scan a website from Safari for malicious content BEFORE you actually navigate to it!
Ok, so only when the stories about windows having malware are they true. But when they are about Macs then your personal observation of OSX forums are the only proof you need.
That sounds fair and logical (for a democrat).
I love the pop-up windows I get occasionally that say a virus has been detected in my Windows software, and all I have to do is download their product to clean it up - on my Mac.
