On top of that:
I have two computers at home. I downloaded the free version of Avast! 5.0 on each. One computer is protected for a year. The other only two months. Naturally, I assumed that both computers would have the same duration.
When I tried to re-register on the other computer, Google could not find this site! In fact, Google could not find any other antivirus site until I finally was able to download Alvira to have some protection.
I have downloaded Avast!'s removal program. Hopefully, when I remove 5.0 from the other computer, I can reconnect with this site.
