Thank you immensely again for the quick reply, the good point and suggestion. When I research my Avast questions or seek general Avast information on the forum, I read all of your posts with great interest as I hold what you have to say in the highest regard so I am very appreciative of your input on my issue. My apologies for the delay in replying - super busy day.
As you suggested, I started Bank Mode and visited several non-banking sites. No problems or error messages from Avast for any of the web sites. Then, I was looking through the settings for something and I noticed in the SafeZone Add-ons section there is an option to add custom web sites to switch to Bank Mode automatically. So, I added several non-banking sites (Amazon and a few others) and when I searched these non-bank web sites in standard mode, I was automatically switched to Bank Mode. Therefore, it appears that your point is right on target.
Again, I truly thank you for all of your help and patience.
