Just an up-date to my toolbar problem.
It's now fixed.All icons, Norton and SpoofStick now showing as they should do.
I won't bore you with all the details.
But basically I did a "Restore Defaults" in "Tools, Internet Options, Advanced, and it now works.
I can only attribute the problem to a suggestion from a different forum of enabling something there.
Something to do with Privacy, I think!
So I decided to do a "Restore Defaults" and just re-set the one option as usual (do not save encrypted files)
Had another look in "View, Toolbars" and there was Norton sitting so pretty like it always used too, clicked it and,
And it WORKED.
Thanks to everyone for the suggestions.
Hope this also works for anyone else who may have the same problem.
