during AVG installation through AVG Download Manager (available at CNET or http://free.avg.com ) you could choose, if you want AVG Free or AVG Trial (30 days). It looks like you have chosen the AVG Trial version option.
You could use "Downgrade" option as soon as the trial license number expires, or just hit AVG uninstall option in menu Start / Control Panel (this option will be showed as well).
Or completely uninstall AVG Trial and install AVG Free.

Another way how to download the full AVG Free installation file is second option on this AVG website:
After downloading this "free" version successfully to my PC, I am getting a countdown message saying my "trial" version will expire in XX days.
In visiting the AVG website, I see no "free" downloads, only "trials".
Anybody know the answer to this?
