Install Linux Malware Detect and ClamAV on CentOS: A Malware Scanner for Linux Operating System
A VPS server can be easily scanned for malware and viruses with Linux Malware Detect and ClamAV. In this tutorial, we’ll install both programs on CentOS and test them out.
So let’s get started,
Step 1: Install Linux Malware Detect
Run the following command to install Linux Malware Detect
tar -xvf maldetect-current.tar.gz
A cronjob task will be automatically created by Linux Malware Detect after the installation is complete.
Step 2: Configure Linux Malware Detect
All configuration settings of Linux Malware Detect are stored in the file /usr/local/maldetect/conf.maldet
# Enable Email Alerting
# Email Address in which you want to receive scan reports
# Email subject of the notification. email_subj="Malware alerts for $HOSTNAME - $(date +%Y-%m-%d)"
# Move the malware to quarantine. quar_hits=1
# Delete any malware detected. quar_clean=1
# Use ClamAV's malware library to scan. clamav_scan=1
Step 3: Install ClamAV
The EPEL repository must first be installed:
yum install epel-release
Next, we install ClamAV using the following command:
yum update && yum install clamav
