The point I'm making is if they are making money by asking us to download Chrome, maybe they will "offer" some freeware fw.
With all the time & effort that went into their fw, I don't think they will give it away.
The avast! fw is a pretty much a basic two way fw, what could you take from it to separate it from Pro fw vs Free?
Make it noisy? Make it one way? Nobody would want it!
