ClamAV is an open-source antivirus engine designed for detecting malicious software, including viruses, trojans, and other harmful threats. Initial development began in 2001, and it is widely regarded for its versatility and reliability. ClamAV offers powerful scanning tools for various platforms, enabling it to identify threats in files, emails, and web content. Its database, which is continually updated by the open-source community, includes signature definitions and heuristics to improve detection rates. ClamAV is particularly popular for use on mail servers and in server environments, where it can serve as a backend scanner for antivirus systems.
Not only does ClamAV provide command-line scanning capabilities, but it also includes a daemon for on-access scanning and a flexible configuration that supports integration with other applications. It is compatible with numerous operating systems, including Linux and Windows, making it a preferred choice for self-hosters seeking to enhance their security posture. As a community-driven project, ClamAV thrives on collaboration and offers a range of extensions and integrations, ensuring it remains effective against evolving cyber threats.
