"The remote Windows host contains an application that is affected by an
incorrect encryption usage vulnerability.");

"The remote host has PowerArchiver version 14.02.03 installed. It is,
therefore, affected by a flaw with the encryption usage.

A flaw exists in the application where the insecure PKZIP encryption
method is used when a user attempts to encrypt files with AES 256-bit
encryption.

Note that Nessus has not attempted to exploit this issue, but has
instead relied only on the application's self-reported version number.");
