Delete your cookies file and start over. IE>tools>internet options>delete cookies button, also go to the advanced tab (internet options)and tic the empty temporary internet files..... box. 

Thanks Mombodog, A good sugestion, but I had already done that. The advanced tab (internet options)the empty temporary internet files..... box.  was already checked so files would be deleted after browsing. I have sent an e-mail request to dell for help but so far no response. My Spy Sweeper program did something but not sure what.I have restored my system to before this happened but that didn't help.
