• Clamav:
  • Installation:
    • Download: https://www.clamav.net/downloads
    • Install: https://docs.clamav.net/manual/Installing.html
    • Configure: https://docs.clamav.net/manual/Usage/Configuration.html

    -------------------------------------------

  • My History:
    • first attempts (not completely documented/recorded), unsuccessful, abandoned...
      $ sudo apt install clamav clamav-daemon
      $ sudo systemctl stop clamav-freshclam
      $ sudo freshclam
      $ sudo systemctl start clamav-freshclam
    • 2025-04-05:
      downloaded:
      clamav-1.4.2.linux.x86_64.deb
      clamav-1.4.2.linux.x86_64.deb.new_key.sig
      clamav-1.4.2.linux.x86_64.deb.sig

      
      installed:

      $ sudo apt install ~/Downloads/clamav-1.4.0.libnux.x86_64.deb
      Note this instruction is cut and pasted from (... link above), but has a typo,
      and should be ... 1.4.2.linux.x86 ...

      
      verify installation:

      $ apt info clamav

      However this command did not work. The 'info' parameter perhaps is not supported in my version.
      But this did work:

      $ sudo dpkg -s clamav

      and showed successful install.

      -------------------------------------------

    • Scan your system with ClamAV::
      • $ sudo clamscan -r –bell -i /
        -r: Recursive scan.
        –bell: Beep when a virus is found.
        -i: Only show infected files.
        Infected files will be listed in the terminal output.
      • or:
        $ clamscan --recursive /
        This executed, though gave error:
        "No such file or directory: /usr/local/share/clamav"
