Hello Roy! sounds like your current AVG setup has some corrupted files in them , leading to these errors. what you have to do , to fix this is the following : download the AVG removal tool and save this to your computers desktop. uninstall your current AVG as normal , when the program installer asks for a reboot , do so. after your computer has booted back up , run the AVG removal tool , this will remove any remnants , regkeys , old folders as possible left over drivers from your previous installation. if you have run the AVG removal tool , it will ask for a computer reboot : do so. after booting back up again , you can go to the AVG site and download a new installer package and install this. If everything goes well , you should now have a correct working AVG installation 
you can download the AVG removal tool here ( 32 or 64 bit , depending on your oprating system. Install AVG on your PC, Mac | AVG installation files Barry AVG VIP/HOF/GURU
