It’s not immediately obvious but you need to decline this offer. Many people correctly clicked to install the update, however, during the installation AVG offer to upgrade your version to the trial version of AVG Pro. This happened recently when it offered an update to AVG Free Summer 2013 version. When you run the FREE version of AVG you will periodically get a message pop up offering the latest version. Recently I have had a lot of calls from people who are being told that their AVG has expired and who are being prompted to pay for AVG protection. A lot of my home customers use AVG free as their main anti-virus protection.
