Firewall Driver

I just found the firewall driver under my card settings and wondered what it does. Ive tried googling and keep coming up with troubleshooting threads. Not quite what Im looking for.

So:
What is it/does it do?
Does it enhance the firewall in some way?

Thanks

not much info here … give as much info as you can, then maybe somone can answer

what did you find … file name
where is it located … full file path
why is it strange / suspicious
