I get these messages regularly but mine are not pop up- they come directly to my mail address. The messages I get are Korean. Also, many other messages for questionable products, investment deals, etc., plus pornography. . Mine started arriving after Yahoo started bombarding their subscribers. Yes, they offered a way to opt out but when I try to access the site I cannot get to the option page. Other members of a Yahoo list are having the same problem. Resigning from the list does not stop it. Apparently one has to take on a new email address and not be involved in any lists with Yahoo.. Cindy
