Infoworld reports that Sourcefire bought the Open Source ClamAV anti-virus project. ClamAV is the engine that powers the free ClamWin anti-virus scanner for Microsoft Windows. I wonder if the corporate ownership of ClamAV will affect ClamWin? I sure hope not. It is one of the few (only?) non-real-time AV scanners for Windows. This is a good thing since most AV apps for Windows can't co-exist because they collide with each other. I depend on ClamWin as a second opinion for desktop security. I usually run it in addition to whatever real-time scanner I'm using at the time (NOD32 these days).
