Here is my experience.
I go to the page you link and see
This file may contain malware and the automatic download has been disabled.
Are you really sure you want to download potential malware? Here's the direct link.I'm not really sure I want to download potential malware, since I don't get that warning with any other coin, but okay, I download it.
Then I put it on a computer and it gives a "connecting" symbol endlessly, presumably refusing to do anything unless I let it connect to a network, unlike any other coin. Not good.

I'm sure you must know that people create offline wallets with cryptocurrencies? i can do that with any currency, but not boolberry? Why?
Sourceforge is more than likely throwing a false positive kinda like how AV software can get triggered by mining stuff.
