fake malware at OS X

Hi, while using Mac Book PRO bumped into virus threat “Malware Crusher”! Damn, I was pretty sure that OS X is safe in case of this plague! As I discovered, this program is not malware itself but obtrusively offers you to install a tool against malware. In the same time it steels your traffic and slows down main processes. Standard way of uninstalling is not working, so I was searching for alter variants and I’ve found this article macsecurity.net/view/148/. Maybe somebody else knows anything about this virus and how to get rid off it?
