In this tutorial, we will show you how to install and configuration of ClamAV on your CentOS 6. For those of you who didn’t know, ClamAV is an open-source (GPL) antivirus engine designed for detecting viruses, malware, and other malicious threats on Linux. It’s easy to use and best for Linux-based Web & Mail servers. In this article, I will show you the step-by-step installation of ClamAV on CentOS 6.x from the source.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of ClamAV on a CentOS 6.

Step 4. Configuring daily scan.
In this example, I will configure a cronjob to scan the
/home/ directory every day:
Add the following piece of code to the clamav_scan file.
#!/bin/bash SCAN_DIR="/home" LOG_FILE="/var/log/clamav/manual_clamscan.log" /usr/bin/clamscan -i -r $SCAN_DIR >> $LOG_FILE
Give our cron script executable permissions:
chmod +x /etc/cron.daily/clamav_scan
