Always handle suspicious files with caution. Trend Micro recommends adding such files to a password-protected archive file or password-protecting document files from being opened before transporting the files across the network. Deep Discovery Email Inspector can also heuristically discover passwords in email messages to extract files.
Deep Discovery Email Inspector uses user-specified passwords to extract files or open password-protected documents. For better performance, list commonly used passwords first.
For information on the password-protected file types Deep Discovery Email Inspector supports, see Password-protected File Types.
