AVG is a security program, therefore, for better uninstall results we strongly recommend to uninstall AVG using the installation log in Windows Safe Mode
Download and install Revo Uninstaller Pro - 30 days fully functional trial version
Start Revo Uninstaller Pro and open the module "Logs Database"
Select the appropriate log by version from the list and press the "Uninstall" button from the toolbar
You will see few popping up windows showing the download and import of the log to your Revo Uninstaller Pro and then the main Uninstall dialog that shows the progress of the uninstall of AVG Antivirus 2013 Free.
Note: If you see AVG Antivirus 2013 Free listed in the "All programs" tab, another approach is to start the uninstall from there and if Revo Uninstaller Pro detects an appropriate log from its database it will be automatically used for the uninstall.
