I'm sorry, but this is just plain ignorant. Weekly coverage of every piece of malware? How much malware have you seen for the Mac period that you can make it out to be a weekly occurrence?
Fanboys acting like no one will fall for this sort of thing obviously haven't been watching the number of support phone calls that Apple has been getting on this issue alone or the fact that Apple (rather quickly) is putting anti-malware into OSX on a 1:1 basis right now. If these types of trojans suddenly go viral so-to-speak, just watch Apple try to keep up. Some of you don't see the forest for the tree here or playing "it doesn't matter" games. I've NEVER gotten a virus on my Win98 or WinXP machine (I have gotten two trojans because they were posing as legit programs and they even functioned as such; they STILL had a backdoor in them keylogging and what not; fortunately AVG picked them right up).
Viruses are old news. If this program wanted to do something malicious, it'd be making more news. Most malware in 2011 is designed to make easy money for a bunch of half-baked scam artists. They aren't as sophisticated as viruses. They don't have to be with so many people world-wide using computers these days. You don't need to catch a billion fish to not be hungry....
Responsible/intelligent/wise people would make a mental note of these issues and how to safely avoid them and move on. Immature people spend all day posting how stupid everyone else is or how Mac users are uber-intelligent creatures that never fall for scams. All of it is a waste of time and a waste of space on Earth. It's a bunch of chest-thumping "I'm the bigger alpha male than the rest of Earth". How useless.
