Hi Ian
Thanks for your input and advice. The only slight problem I have with changing things is the possibility of unintended consequences. For example, we have a Brother Printer which has the ability to scan a document directly to a PDF file on a PC. A feature I use quite a lot. The printer is connected to our PC's via the Local Area Network over Wi Fi. Some years ago this scanning to a PDF stopped working. I believe this was after a Windows update. The only clue was a message on the Printers Screen which said "if you can't connect check the PC firewall settings". The solution was extremely difficult to find on the Brother's Self Serve Support web pages. This involved opening a specific local port for inbound LAN UDP traffic (implying that it will still be closed for WAN traffic) and to do this you had to dig deep into the advanced firewall settings, a place I don't normally go. However, after a couple of days of digging this information out and applying it, the problem was resolved. So for the moment I will live with the AVG nonsense just to see if the next update fixes the problem. If not then I will take your advice, uninstall AVG and use Windows Defender.
