Clam AntiVirus

So I was looking through the antivirus downloads here at Major Geeks this morning (here http://www.majorgeeks.com/downloads29.html) for no particular reason, just to see if anything new and fantastic or something I had overlooked was listed.... not really in need of anything..... and I saw that there is two different Clam AV applications. One of these I have used off and on, the other I haven't used. At least I don't think I have, but I can't be sure. So, what's the difference between them? Are they the same? Here's the links....

Both are open source and free, neither has real-time active protection (as far as I know)
:confused So, can someone shed light on this?
Thanks.
