Avast Firewall whole directory block?

I’ve just installed this Avast Antivirus, and its firewall took over Windows 7 Firewall thus all the firewall policies that I had don’t work.
I have to configure this Avast firewall. Is there a way to block a whole directory? It’s just too much work to manually block program by program.

Yeah… that doesn’t help. There are a lot of directories in which there are .exes that need to be blocked.
Doing that manually will take forever

Why do you have so many things that you want to block ?
What are they ?
