The ndb file extension is associated with Clam AntiVirus (ClamAV), an open-source antivirus program for Microsoft Windows, macOS (OS X) and Linux.
An ndb file is a plain-text signature database. It contains custom signature definitions that ClamAV uses to identify viruses and other malware.
The file belongs to ClamAV's collection of virus-detection databases and is intended for use by the antivirus scanner rather than as a standalone document.
To inspect an ndb file, open it with a plain-text editor. The signature definitions can be read and edited as text.
To use the signatures, place the file in the ClamAV virus database directory and reload or restart ClamAV. The exact database location and reload procedure depend on the installation and operating system.
An ndb file is not a document or media file, so it has no useful general-purpose conversion format. To change it, edit the signature definitions as plain text or create new signatures using ClamAV's signature tools.
