It's designed to let you run your own private ClamAV database mirror on your network, which you can then serve to local FreshClam clients via HTTP instead of having every machine download directly from the public servers.\n\nThe tool uses DNS queries to check for new database versions before downloading, so repeated runs don't waste bandwidth. It stores databases and patches locally (by default in ~/.cvdupdate), rotates old patch files and logs automatically, and includes a built-in test HTTP server for quick validation. You can customize the database directory, nameserver, and logging behavior via a JSON config file, and integrate it into cron jobs or other automation for hands-off updates.","worth_installing":"Yes. If you operate a ClamAV deployment with multiple clients or restricted external network access, this tool is the standard way to host your own database mirror. It's actively maintained, has no known vulnerabilities, installs with low friction, and carries a permissive license. Not relevant for single-machine ClamAV setups that can reach the public servers directly."},"id":"cvdupdate","links":{"html":"https://skillfed.io/packages/cvdupdate","md":"https://skillfed.io/packages/cvdupdate.md","pypi":"https://pypi.org/project/cvdupdate/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-10-03","license_spdx":null,"license_treatment":"permissive","name":"cvdupdate","python_support":"unspecified","summary":"ClamAV Private Database Mirror Updater Tool"},"popularity":{"monthly_downloads":959401,"position":4638,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.2.0"}
