DDOS protection is now a lower problem.
The real problem is the massive DOS which can't be stopped.
Even tough your provider is doing a good job filtering the flood attack
he will preferre blocking your IP for a few hours until the attacker stops.
The reason for that is the that while you're being attacked ,your provider is loosing alot of bandwidth on your ass .
EDIT: And yeah this program is a waste of memory as someone said already before.
