BitDefender Antivirus Scanner for Unices is a versatile on-demand scanner built for Linux and FreeBSD systems. It uses BitDefender architecture-independent scanning engines. These are specialized data analysis routines and malware signature definitions, since many viruses can be identified based on a distinctive code pattern. To identify unknown viruses, the engines can perform a heuristic analysis, searching for several features characterizing viruses.

It is a highly customizable application and capable of script and extension-based integration with various applications such as file managers and mail clients. It consists of both command line (bdscan) and graphical user interface scanner (bdgui), which offers better integration with desktop environments
