It happened to me and everyone who has a yahoo email that is in my other address book is sent back and forth. I don't know so I disabled my yahoo email. I love freecycle and I think it is one of the yahoo deals like that which is sending it around.If you go to Start/Run/type in restore and choose a date say a month prior to the time you began getting these......there's achance that you can get rid of it. But, I took my tower into Staples.....they have a free cleaning and setup once a month on a Saturday and I got rid of mine.........finally, I hope anyways. Best of luck. Ruth
