The newer Malwarebytes builds allow for some form of update randomization, albeit from the command line... i.e. "mbam-msp.exe /schedule /update /starting 03/28/2011 07:00:00 /hourly /every 4 /random /silent"

Why has this functionality not been built into the KAM profile create/edit page?  It you pick an update time and frequency, i.e. 7:00 AM every 4 hrs, you will have every machine at an office run the update to download a 5+ mb update file at the exact same time every time it goes out, which is a problem for larger organizations.

Also, why is the desktop icon hidden?  Is there an option to unhide it?
