How to Install and Use Linux Malware Detect (LMD) with ClamAV as Antivirus Engine on Fedora Server

 

Installing LMD on RHEL/CentOS 7.0 and Fedora 22-24

LMD is not available from online repositories, but is distributed as a tarball from the project’s web site. The tarball containing the source code of the latest version is always available at the following link, where it can be downloaded with:

Step 1 :-  wget https://www.rfxn.com/downloads/maldetect-current.tar.gz

Step 2 :-  tar -xvf maldetect-current.tar.gz

Step 3 :-  ls -l | grep maldetect

Step 4 :-   ./install.sh

Configuring Linux Malware Detect

The configuration of LMD is handled through /usr/local/maldetect/conf.maldet and all options are well commented to make configuration a rather easy task. In case you get stuck, you can also refer to /usr/local/src/maldetect-1.4.2/README for further instructions.

In the configuration file you will find the following sections, enclosed inside square brackets:

EMAIL ALERTS
QUARANTINE OPTIONS
SCAN OPTIONS
STATISTICAL ANALYSIS
MONITORING OPTIONS

Important:-
Please note that quar_clean and quar_susp require that quar_hits be enabled (=1).

Summing up, the lines with these variables should look as follows in /usr/local/maldetect/conf.maldet:
