My internet security trial has finished but I do not wish to purchase and wish to continue to use AVG free. However, the instructions for resetting do not work. Do I need to uninstall completely and re-install?
That is the article that I've been using to try to rectify the problem. I actually needed to call your Technical Support line to get the problem fixed as the instructions in the articke are WRONG (for Windows 10, at least).
Phil,
