If you purchased avast pro through either an avast reseller or through the avast web site @ share*it then you should have received an email with your registration.
Where did you purchase your copy of avast pro ?
There should be nothing stopping you from installing avast pro without a license key you can use the demo key which will give 60 days unrestricted use, so you have plenty of time to get your registration/license key.
Here’s the page to register avast! home:
http://www.avast.com/eng/home-registration.php
To use the Home Edition, you should register it, however, after initial installation you have 60 days to trial the product (as with all avast! antivirus products) before you must complete registration. The registration process is very easy, and will take you only a couple of minutes.

You can get a free trial of avast! professional, but if you want a serial for that, you’ll have to pay for it.
avast! home is free for home use, and has exactly the same detection of viruses, worms, Trojans and spyware.
In the site www.baixaki.com.br the software and free for decrease but her nao speaks the serial one and in the
site of the avast nao has then I am going to have that buys the license?

Licença: Gratuito
I think my Portuguese is good enough to say that means ‘licence: free’.
You don’t have to buy a licence for home use.
You don’t need the Professional version, you can use the free Home version.
Frank, you’re fully right.
