As far as I'm concerned (and I use a lot of different malware cleaning stuff) I don't think I'll ever buy or try again something made by Greatis.
I didn't like their claims about Rootkit Unhooker and the total uselessness of Unhackme, touted by them as one of the best antirootkits ever, but completely unable to recognise a lot of different rootkits I stumbled upon.
So I'll keep relying on my not so common sense to protect me and on several trusted applications to do the cleaning on customers' infected machines, being well aware that the first useful instrument to fight malware is a bootcd with the needed tools.
