When you cannot update
Since you cannot use the Internet, manually download the definition updates
from another computer, save them to a flash (usb, pen, thumb, jump) drive or CD and transfer to the infected machine. Then just double-click on mbam-rules.exe
to install the update. If you cannot transfer or install from the infected machine, try installing the file directly from the flash drive to your machine.
Mbam-rules.exe is not
updated daily. Another way to get the most current database definitions is to install MBAM on a clean computer, launch the program, update through MBAM's interface, copy the definitions (rules.ref
) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system.

If you cannot see the folder, then you may have to Reconfigure Windows
to show it.
