  • ClamAV freshclam failure

    Hi

    If your ClamAV is not correctly receiving updates to daily.cvd, then the best way to correct this is as follows:
    SSH into server
    stop clamav
    stop freshclam
    cd /var/clamav
    delete the following 3 files
    main.cvd
    daily.cvd
    mirrors.dat
    start freshclam and clamav
    run freshclam -v
    exit out of ssh
    below is the test for clamav from one of our server which failed, and the above worked to bring it into normal function
    I hope that helps a little
    Many thanks
    John
