No Internet after installing avast!

Clean Installed avast! IS v6.0.1289. now I can’t connect to the internet. Avast firewall is stopped and when i click start, it fails! therefore i did a manual installation with firewall deselected. now internet is ok, but i need to run the firewall somehow.

Please send me your “\Program Files\AVAST Software\Avast\Setup\setup.log” file to kurtin@avast.com, thanks!
