Hi, my problem is that on trying to open the interface I just keep getting a box showing that my " Trial has expired " and please renew but I am using " AVG Free Version " and have not had any trial ?
I then tried all the possible fixes, Repair in Control Panel NO, download a removal tool and ran that which did not recognise AVG on my system ? NO Fix, and finally tried the complete uninstall of ALL of AVG files and re-installed the Free Version from an AVG site but it still shows the Trial Box, so please EXPLAIN  if possible.
P.S.
Never had this problem before on any of my PC's ???
