Why do I get an error about an incorrect byte size when downloading MATLAB products?

When I download MATLAB products, I get one of the following messages:

ERROR: There was an error while downloading <filename>. Expected <filesize> bytes, but received <filesize> bytes. We recommend that you retry this download. What would you like to do?

or

ERROR: The following error was detected while downloading <filename>:
Wrong number of bytes: Expected <filesize>, got <filesize>
Would you like to retry downloading <filename>?

This error occurs when antivirus or security software is installed on your computer and blocking the download. Please temporarily disable the program and retry the download.
