Clam AntiVirus (ClamAV) is a free, cross-platform antivirus software tool-kit capable of detecting many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner. The application was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, Mac OS X, OpenVMS, OSF and Solaris. At one time it had a native version available for Windows, but that project has been ended.

Both ClamAV and its updates are made available free of charge.

Sourcefire, a maker of intrusion detection products and the owner of Snort, announced on 17 August 2007 that it had acquired the trademarks and copyrights to ClamAV from five key developers.
