Norton Antivirus, developed by Symantec, uses vdb files to store virus-definition data. These definitions help the program identify and remove known viruses and other malware during a subscription period.
The files are part of Norton Antivirus's internal update system. They are installed and managed by the program rather than used as documents that can be opened or edited by the user.
This format is associated with Norton Antivirus for Microsoft Windows. A vdb file should normally be handled by the Norton software that created or downloaded it.
A vdb file is intended for internal use by Norton Antivirus on Microsoft Windows. It should be left in the location where Norton installed it and does not need to be opened manually.
To use the definitions, run Norton Antivirus and use its built-in update feature.
There is no practical conversion for a Norton Antivirus vdb file. It contains proprietary virus-definition data, not user documents or data intended for export.
Keep the file under Norton Antivirus's control and obtain updated definitions through the program instead of editing or converting it.

VistaDB is an embedded relational database engine developed by eSymmetrix, Inc. for Microsoft Windows software. Applications use its database files to store structured information in tables and related database objects.
The VistaDB engine has been licensed for use in several software products. A .vdb file normally belongs to the application that created it and may be one of several files in that application's data set.
The format is intended to be used through VistaDB-based Windows software rather than edited directly. Its accessibility depends on the application and a compatible VistaDB engine version.
Open a .vdb file with the VistaDB-based Windows application that created it. If the file belongs to Family Tree Maker, open it through that program rather than opening the file directly.
Other VistaDB files require the original application or another program that includes a compatible VistaDB engine. Renaming the file or opening it in an unrelated database program will not make it readable.
There is no generally applicable standalone conversion method for VistaDB database files. If the file opens in its original application, use that program's database export or data-transfer features to create a supported format.
