As I know they develop their antivirues. But not they destribute antivirus for free.
Antivirus will be free, but users will need to pay if Romad will find and blocked virus on user's PC.
So if no viruses will be found no paying.
But if it will be no listing on the exchanges the payment for antivirus will be only in fiat.
The idea was that the client would pay for a license in Fiat, and Romad would convert Fiat into cryptocurrency and pay dividends to holders of Romad tokens. Of course Romat should to be on exchanges. And this is not difficult thing because it is ERC20.
