avast! Home Edition is now free of charge for HOME users for
NON-COMMERCIAL use. If you are not a home user, or you use your computer
for profit, the avast! Home Edition is not licensed for such use, and you
are asked to use the commercial version - avast! Professional Edition.

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.
