Sourcefire, a maker of intrusion detection products, announced on Friday that the company had acquired the intellectual property and copyrights to the open-source antivirus project, ClamAV, from five key developers.

Under the terms of the agreement with ClamAV founder Tomasz Kojm and four other members of the project, Sourcefire acquired the rights and trademarks to the project, the five developers’ copyrights and all Web content. Sourcefire, which already owns rights to the open-source Snort intrusion detection system created by company founder Martin Roesch, said it will maintain ClamAV much in the same way as it has done with Snort.
