Hi Bob, That’s the reason I exist. To amaze people! What defines common sense?
Albert Einstein said, " Common sense is the collection of prejudices acquired by age eighteen."
It’s rather ironic that the very definition of common sense may be a bit challenging. Now, this may seem comical to those who already possess common sense, but this attempt is not for them anyway. After all, if you have common sense, you probably know what common sense is.
The Merriam-Webster OnLine Dictionary lists two definitions that compliment each other:

1: the unreflective opinions of ordinary people
2: sound and prudent but often unsophisticated judgment

This helps, but I don’t think it actually gets right down to what common sense really is. Don’t look at me for a more accurate definition, because I don’t have one. You either know what common sense is, or you think you know what common sense is. I’m just glad there are help forums for those of us who need help regardless of whether it derives from a lack of common sense or not.
I would like to add that Avast is a wonderful product and I’m grateful for all the help found here in the forums.
