    clamd-0.102.3-13765.el7.art.x86_64
    clamav-milter-debuginfo-0.104.3-25721.el8.art.x86_64
    clamav-db-0.104.3-25721.el8.art.x86_64

    And remove them using the commands below:

    # yum remove clamd-0.102.3-13765.el7.art.x86_64
    # yum remove clamav-milter-debuginfo-0.104.3-25721.el8.art.x86_64
    # yum remove clamav-db-0.104.3-25721.el8.art.x86_64
