Installing ClamAV on CentOS 8

ClamAV is an open-source antivirus engine that is designed to detect various types of malicious software, including viruses, malware, and other harmful threats. It provides a command-line scanner, as well as a scalable multi-threaded daemon for scanning files on-demand or in real-time.

Here are the steps to install ClamAV on CentOS 8:

1. Open a terminal or SSH into your CentOS 8 server.
2. Update the system's package repository by running the following command:

   sudo dnf update

3. Install ClamAV and its dependencies by executing the following command:

   sudo dnf install clamav clamav-update

4. Once the installation is complete, update the ClamAV virus database by running the following command:

   sudo freshclam

5. Start the ClamAV daemon to enable real-time scanning:

   sudo systemctl enable clamd@scan

   sudo systemctl start clamd@scan

6. Configure ClamAV by editing the main configuration file:

   sudo vi /etc/clamd.d/scan.conf

   Make any necessary changes, such as setting the desired scan options or adjusting the log file location.
7. Save and close the configuration file.
8. Reload the ClamAV daemon to apply the changes:

   sudo systemctl reload clamd@scan

You have successfully installed and configured ClamAV on your CentOS 8 server. You can now use the ClamAV command-line scanner or integrate it with other applications to scan files for malware and viruses.
