Firewall Problems

Hello there! I’ve just installed Avast 4.7 and it shuts down internet connection. How can i fix it??? :((((

Did you set the apropiate rules in your firewall for avast?
What firewall do you have?
What OS?

What do you mean shuts down Internet Connection, that isn’t a function of avast, it isn’t a firewall, can you expand on what is happening ?
What error messages, etc. are you getting ?
