I just wanted to report back on the problem I had.
I read the links provided by hamluis. I was going to reset my computer as advised. A few moments (before I started the reset procedure) later I clicked on one of the tabs to close a window and I got a error message that I was being disconnected from the internet. Just then another window poped up that I had never seen befor.It said that toolband.dll was running at the time of the error.
I googled toolband.dll and found out that it could be malware or it could be installed by Cannon or Lexmark.
I have a Lexmark computer so I went searching. I found out how to manage add - ons and disabled the Lexmark tool bar and Lexmark browser helper add-ons. That resolved the problem. I would like to have the Lexmark tool bar back on the screen as my wife used it quite a bit but not at the expense of being cut off all the time.
Anyway, I am tardy in reporting my results.
Thanks for the help hamluis.
