How to manually update Bitdefender Scanner for Unices

Bitdefender Antivirus Scanner for Unices is a versatile on-demand scanner for Linux and FreeBSD systems. The stand-alone scanner protects both UNIX-based and Windows-based disk partitions by scanning for viruses and spyware. Easy to use graphical user interface complements a powerful command line interface that fully supports operating systems scripting tools. The scanner works stand-alone without needing any Centralized Management or local Update Servers.

If you have no Internet access, you can perform a manual update for the Bitdefender product. The update server hosts a archive, released every day, containing all of the scanning engines and virus signatures updates up to the release date. You can use this archive to update Bitdefender.

Considering BDPATH to be the path to the Bitdefender Antivirus Scanner for Unices installation directory, we will have the following:

  • Linux BDPATH is /opt/BitDefender-scanner
  • FreeBSD BDPATH is /usr/local/bitdefender-scanner. To manually update the product, follow these steps:


  1. Download the cumulative zip archive which contains the latest product and update signatures (updated daily):
    • For 32-bit systems: click here
    • For 64-bit systems: click here
  2. Extract the contents of the zip file to the $BDPATH/var/lib/scan/ directory, overwriting the existing  files with the newer ones if necessary.
  3. Set the proper permissions. After extracting the zip archive, you must set the proper owner and permissions, by running the following commands.

    # chown bitdefender:bitdefender $BDPATH/var/lib/scan/Plugins/*

# chmod 644 $BDPATH/var/lib/scan/Plugins/*
