I think if the payment depends on the attack of course we as anti-virus users have to pay a lot of costs to pay and of course it is very burdensome for us as users, I think maybe the anti-virus Romad is the same as other anti-virus where our users only pay once when we first download it. but if indeed as you say that users have to pay every time there is a hacking attack of course people will think twice about using anti-virus Romad, because obviously it's too expensive.
