ClamAV Unofficial Signatures Updater is a script that provides a simple way to download, test, and use third-party ClamAV signatures. It checks for updated unofficial clamav signature database files and can download them. It randomizes download time to help distribute the load more evenly for the database host mirror sites. Signature bypass entries can be created for temporarily resolving false-positive issues with third-party signatures. It can report which mirror site a download came from. It reports if a downloaded database is actually different than the running copy. Many other features are supported.
