How do I get the stuff off my computer you added today?

My account at Norton has always been a mess and today I can get no help in understanding why a new horizontal bar and a large box suddenly appeared today on my screen which also erased papers I was drafting and is not appreciated.  After several hours, I ended up having to sign up for a new account which makes either three or four accounts lurking inside Norton.  Who will explain the gibberish to me?

I don't expect the bizarre accounts to be fixed by Norton because it always goes awry...just give me back my screen so I can do my work.    By the way, anyone who would be a MS 10 in the absence of a MS 9 must be crazy.  MS plays with us consumers.
