It does make it a little more difficult. How to update Malwarebytes Anti-malware without Internet Connection | Kioskea.net
Hi Hoppy! I see you beat me to it.
Actually this procedure needs to be followed with any machine that needs updates of any kind, but lacks an Internet connection.
The only caveat is knowing how large the update/file is, and having a device large enough to accept it.
MBAM rules updates are usually in the 7 to 8MB range. There will be times that there may also be program updates, and they can vary.
