Hello Maria,
It is to keep you informed that you might have installed the trial version of the AVG Antivirus program and that's the reason you are facing the issue. Please run the  AVG remover tool : http://aa-download.avg.com/filedir/util/AVG_Remover.exe to completely uninstall your previous installation of AVG program from your PC. Once uninstalled please follow the instructions on the article http://avgread.me/1cvJ6DX to reinstall your AVG program.
