Hi paulrickca,
First, I am really sorry to hear about the problems you are having. Second, it would be very helpful to get log files from you to see why you aren't able to connect. The log file is found in C: program data, Avast Software, Avast, Log. It is the secureline.txt file.
It is strange that it's not working after the update, so it is something we want to look into right away.
Can you also please post the support ticket number here and I'll push that for you?
Once again, apologies for this issue. We'll do our best to resolve it for you.
Regards,
Davidek
