The well known scareware mac defender that has been around the last few days, was to be killed by Mac OSX Security Update 2011-003 but the scareware developer team killed the security suite within 8 hours! Apples Security suite isn't able to track MAC Defender anymore and the app looks legit again.
A new race has began between Mac OSX Developers and the on the come scareware team. Windows users now can look at apple mac osx with an smile ;) the malware future has begun and there are more to come!
