I downloaded Spyware Cease and then found my p.c. home page was bombarded with numerous simultaneous Bing homepages (which I did not want) and my search window , which I had set to Google, sent me to all kind of sites I did not want. After trying all sorts of things, I ran Norton which found no problems. I eventually downloaded Malwarebytes and it found 26 Trojans. I deleted them, and no problems! So while it could be Spyware Cease is not the culprit, it would be useful to hear of any comments from other users.
