By leveraging a combination of user-defined passwords and message content
               (subject, body and attachment names), Trend Micro Email
                  Security can
               heuristically extract or open password-protected files, namely, archive files and
               document
               files, in email messages to detect any malicious payload that may be embedded in those
               files.
You can add or import user-defined passwords to help Trend Micro Email
                  Security efficiently extract or open password-protected
               files for further scanning.
NoteFile password analysis is only applied for virus scan, and not for DLP or content
                              filtering.
