How to completely uninstall MetaDefender ICAP?

Check Your Version:

This article applies to all MetaDefender ICAP releases deployed on Windows and Linux systems.

Info

If you installed using an ignition file (located at C:\OPSWAT\mdicapsrv.conf or /etc/opswat/mdicapsrv.conf), this file is not removed automatically by any of the steps below - you must delete or manage it yourself.

Windows

  1. Uninstall the software from Apps & Features or the Control Panel.

  2. Remove leftover Registry keys (if any exist):

    • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\OPSWAT\ICAP Server

    • Computer\HKEY_CURRENT_USER\Software\OPSWAT\Metadefender ICAP Server

  3. Remove leftover folders (if any exist):

    • C:\Program Files\OPSWAT\Metadefender ICAP Server

    • C:\ProgramData\OPSWAT\MetaDefender ICAP

Linux

  1. Uninstall the ICAP software

Debian/Ubuntu (deb-based systems):

sudo dpkg --purge mdicapsrv

This single command uninstalls the package and removes its configuration files.

RedHat/CentOS/Rocky (rpm-based systems):

sudo yum remove mdicapsrv

  1. Ensure all remaining files are removed (both distro families):

sudo find / -name "mdicapsrv*" 2>/dev/null

e.g. directories commonly left behind include:

/var/lib/mdicapsrv /etc/mdicapsrv /usr/lib/mdicapsrv /usr/share/mdicapsrv /var/tmp/mdicapsrv /var/log/mdicapsrv

  1. Remove any that the find command turns up:

sudo rm -rf <directory_name>
