Mamutu - 0day malware protection

Mamutu is brought to us by the fine folks over at Emsisoft, the people responsible for the fine virus remover A-Squared. Mamutu is a behavior based program that doesn't rely on a signature database; it monitors all processes for suspicious behavior. It's available as a free trial, and I'm actually contemplating paying for it (especially after the events detailed here: http://forums.majorgeeks.com/showthread.php?t=160771). So if anyone here has some info about it; a review, whatever, please post your thoughts and experiences. It seems to be somewhat unknown on the web, so maybe it's new, I don't know. Alternatively, if anyone knows of a similar utility that's free, please post a link or something....
THANKS!
