Installing ClamAV on Ubuntu 22.04

ClamAV is an open-source antivirus engine designed for detecting malicious software such as viruses, trojans, and other malware. It can be used to scan files and directories on your Ubuntu server or desktop, providing an additional layer of security to your system.

Step 1: Update System

To begin, it is recommended to update your system packages to their latest versions. Open the terminal on your Ubuntu machine and run the following command:

sudo apt update && sudo apt upgrade -y

Step 2: Install ClamAV

Now, let's install ClamAV by executing the following command in the terminal:

sudo apt install clamav clamav-daemon -y

During the installation process, you'll be prompted to configure the clamav-freshclam package. Choose "Yes" to allow Freshclam to regularly update virus databases.

Step 3: Update ClamAV Virus Databases

After the installation, update the ClamAV virus databases to ensure you have the latest detection capabilities. Run the following command:

sudo freshclam

Step 4: Perform a System Scan

Now you can use ClamAV to scan specific files, directories, or the entire system. For example, to scan the /home directory, run:

clamscan -r /home

This command will recursively scan all files and subdirectories within the /home directory.

Step 5: Schedule Automatic Scans (Optional)

To enhance security, you can set up automatic system scans by configuring the clamav-daemon service. This ensures regular monitoring of your system for potential threats. For more information on scheduling scans, refer to the ClamAV documentation.
