[Defender Pro] Suspicious Code: /wp-content/plugins/snapshot/lib/Snapshot/Model/Destination/ftp/ph

Hi,

I have a notification from Defender:

/wp-content/plugins/snapshot/lib/Snapshot/Model/Destination/ftp/phpseclib1.0.10/Crypt/Base.php

What should I do? Why is a plugin from you marked as Suspicious?
