Install ClamAV

To install ClamAV on Debian or Ubuntu Linux

  1. Open Terminal from the Applications menu, and execute the following command:
    • sudo apt-get install clamav clamav-daemon clamav-freshclam clamtk
  2. This command will install multiple ClamAV packages. More information about these can be found below.
    • clamav: This is the command-line virus scanner and engine. It can run scans on demand from Terminal, using the command clamscan.
    • clamav-daemon: This package allows ClamAV to be run on a schedule, as an on-access scanner.
    • clamav-freshclam: This package enables automatic updates for ClamAV.
    • clamtk: This is the GUI frontend for ClamAV.
  3. Once these packages have been installed, ClamAV can be run by opening the ClamTk application from the Applications menu.

To install ClamAV on CentOS or Red Hat Linux

  • Open Terminal from the Applications menu, and execute the following commands:
    1. sudo yum -y install epel-release
    2. sudo yum clean all
      • This step is necessary because ClamAV is not included in the default yum repository
    3. sudo yum -y install clamav-server clamav-data clamav-update clamav-filesystem clamav clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd
    4. sudo systemctl enable clamd@scan.service
      • This will enable the ClamAV daemon to run scheduled scans automatically
