Since it seemed like the problem was with the browser, I decided to download Mozilla and see if I could access the sites - and it worked. I can access the sites with Mozilla but at the same time cannot access them with Internet Explorer.
So, is it a problem with Internet Explorer or is it a virus? I've done scans on both computers and they appear clean and I can't find any information on the Microsoft webpage.
I'm going to bed now and will worry about it tomorrow.....after the sew-in, and after bringing Chesty home.
