I've been a user of ClamAV (and its Windows cousin, ClamWin) for years. Needless to say, I was very pleased to hear about the AntiVirus Fight Club Results. This was, according to the site, an "all-out public test of different anti-virus vendors to see how they really compare." The field was impressive, though there were some players that weren't included that I would like to have seen (specifically FSecure, NOD32, AVG, TrendMicro, and Panda). Having done a fair amount of research on AV solutions a little over a year ago, I wasn't surprised to see Kaspersky at the top of the heap. I was, however, pleasantly surprised to see ClamAV right up there, along with Norton. In some cases, ClamAV was substantially better than some of the other choices. Having only personal experience to go on, I always thought that ClamAV was one of the best, but I have never had the time (or, to be honest, the inclination) to do extensive side-by-side testing. I thought ClamAV was one of the best, and as an advocate for all things Open Source, I actively hoped it was one of the best, but I never had solid proof. Until now. Kudos to the ClamAV folks. Nicely done.
On a related note, ClamAV was recently acquired by Sourcefire, the folks who brought us Snort. As you may recall, Sourcefire went public this last March which was, I think, I good thing. I've used Snort for so long I don't even remember when I first started tinkering with it. Now with the acquisition of ClamAV, the idea of further integration between Snort and ClamAV is certainly appealing. I do have one concern with regard to Sourcefire and Snort, though. Prior to the release of GPL 3.0, the Snort license stated that it was covered by GPL 2.0 or later. Once GPL 3.0 was released, however, the license was quietly changed to state explicitly that Snort was covered by only GPL 2.0. What does this mean? Frankly, I'm not completely sure. I've read a lot of posts from Marty Roesch (Mr. Snort himself) and lots of others. Some claim that the change means nothing. Others are claiming that this is the death knell. Personally, I'm not sure what to think. I haven't stopped using Snort. I still love Snort and don't have any plans to give it up. Not yet, anyway. I have, however, started brushing up on Bro IDS, just in case I need to jump ship.
