It assumes that such a file can be a zip bomb and should not be
allowed to deplete system resources. Action is taken on the file only because of
its size, not because of any indication that it contains a virus or other violation. The two files were inside the ZIP file and were remove buy policy rule.  Everything inside a ZIP is assumed to a virus.
The other violation was the encryption password all of these by policy are assumed to a virus.

You can test by ticking the rule, then disable. Send the user an e-mail from gmail/yahoo a file with the an image that you know gets blocked to see if that is the case.
