clamtk is a frontend for ClamAV (Clam Antivirus). It is intended to be an easy to use, light-weight, on-demand scanner for Linux systems. Although its earliest incarnations date to 2003, clamtk was first uploaded for distribution in 2004 to a rootshell.be account and finally to Sourceforge.net in 2005. At the end of 2013, it was moved to a Google Code page, then to Github, Gitlab, and Bitbucket. It is now 2024 and for some reason development is still going. In fact, February 2024 marks 20 years of activity (of being publicly available, that is).
