I would advise you to fill in all fields, if you want to register
Me......?.....I have no problem with this.... it was you who started this topic
Pondus, it is addressed to those who did not come to a license key by mail.
And you don`t need no key in the e-mail if you register online, as the pdf doc shows on page 8
Pondus,
avast! Free Antivirus 5, you can register in two ways. The first way is to fill out a form on the site, and the second way to register through the avast! Free Antivirus 5. I am experimenting with both ways and check-in both cases passed successfully. Shall make a reservation, that every man chooses which way to sign for him more comfortable.
AK 47, you clearly started the topic asking for help on a topic that doesn't require any, normally, so I'm now wondering what your point was exactly 
Logos,
my problem was that I did not receive an email with the license key. Perhaps due to the fact that I badly speak in English, I was not so understood. The reason for absence was solved simply, I have 3-4 times, tried to register via the form on the site Avast. Registration was successful and they sent me a license key for e-mail.
As I wrote the issue resolved. Further continuation of this theme leads to empty flood.
Everyone who took part in the discussion, thank you for your attention.
