In avast! licensing scheme there are two conditions which qualify the user for free non-limited usage of avast! 4 Home. The rules are clear: home AND non-commercial use.
1) it must be the home usage - so any organisations (non-profit or commercial) are disqualified.
2) there should not be any commercial activity done on the computer which is to be protected by avast!,
i.e., if you use it to make some profit, you also do not qualify for avast! Home usage, even on the home computer.
So both conditions should be met for free program!
Anyway, you can have more than one computer in your house and use the same Registration key...
