Well avast isn't a firewall and is only checking a very limited subset of ports, those commonly used for exploits, DCOM, etc... So a firewall is an essential part of your system security.

You may be disappointed as it looks like the avast firewall will initially only be available as part of a suite. But the avast anti-virus should still be available as a stand alone download, for those of us that like to choose individual security products.
