This guide will help you automatically scan all FTP-uploaded files for viruses using ClamAV<\/strong> and Pure-FTPd<\/strong>.<\/p>\n\n\n\n

\ud83d\udd27 Step 1: Install ClamAV via WHM<\/h3>\n\n\n\n
    \n
  1. Log in to WHM<\/strong> as root.<\/li>\n\n\n\n
  2. Navigate to:
    cPanel \u2192 Manage Plugins<\/code><\/li>\n\n\n\n
  3. Locate clamavconnector<\/strong>.<\/li>\n\n\n\n
  4. Check the box \u201cInstall and Keep Updated\u201d<\/strong>.<\/li>\n\n\n\n
  5. Click Save<\/strong> at the bottom.<\/li>\n\n\n\n
  6. Wait for the installation to complete.<\/li>\n<\/ol>\n\n\n\n
    \n\n\n\n

    \ud83d\udee0\ufe0f Step 2: Enable Upload Script Trigger in Pure-FTPd<\/h3>\n\n\n\n

    Edit \/etc\/pure-ftpd.conf<\/code>:<\/p>\n\n\n\n

    nano \/etc\/pure-ftpd.conf<\/mark><\/p>\n\n\n\n

    Find the line:<\/p>\n\n\n\n

    CallUploadScript no
    <\/mark>
    And change it to:

    CallUploadScript yes<\/mark>
    Save and exit the file.


    \ud83e\uddea Step 3: Create the ClamAV Upload Scan Script
    Create the file \/etc\/pure-ftpd\/clamav_check.sh:

    nano \/etc\/pure-ftpd\/clamav_check.sh
    <\/mark>Paste the following content:

    #!\/bin\/bash
    # Max file size to scan (10MB in bytes)
    MAXSIZE=10485760

    if [ \"$UPLOAD_SIZE\" -le \"$MAXSIZE\" ]; then
        \/usr\/bin\/clamdscan --remove --quiet --no-summary \"$1\"
    fi
    <\/mark>
    Make it executable:
    chmod 755 \/etc\/pure-ftpd\/clamav_check.sh
    <\/mark>

    \ud83e\udde9 Step 4: Enable the Upload Script Daemon
    Run this command to start the upload script daemon:
    \/usr\/sbin\/pure-uploadscript -B -r \/etc\/pure-ftpd\/clamav_check.sh

    <\/mark>
    To ensure it starts on boot, add it to rc.local:
    echo \"\/usr\/sbin\/pure-uploadscript -B -r \/etc\/pure-ftpd\/clamav_check.sh\" >> \/etc\/rc.d\/rc.local<\/mark>

    Make sure rc.local is executable:
    chmod +x \/etc\/rc.d\/rc.local
    <\/mark>
    \ud83d\udd01 Step 5: Restart Pure-FTPd
    service pure-ftpd restart
    <\/mark>
    \u2705 Done!
    Now, every uploaded file under 10MB via FTP will be scanned by ClamAV.
    You can increase the scan size limit by changing the MAXSIZE variable in the script.
