I don't know if C|Net actually provides the current version of MBAM or if that is a typo since the current version is 1.46. Regardless, it is likely a rogue that is giving the message to purchase the program. MBAM is free for personal use.
I suggest you try the random installer from here: http://mbam.malwarebytes.org/program...-installer.php
It runs as explorer.exe and the Window name is random.
