Fangfrisch (German for "freshly caught") is a sibling of the Clam Anti-Virus freshclam utility. It allows downloading virus definition files that are not official ClamAV canon, e.g. from Sanesecurity, URLhaus and others. Fangfrisch was designed with security in mind, to be run by an unprivileged user only.
