Yes some link to dangerous websites My Norton security has given me 6 warnings within the last month. You have ads with catchy titles eg( 4 stages to a heart attack) then you get some guy talks talks talks for 20 min - 1/2 hour before he tries to sell you something. You have ads that show pictures that make you click a page for each picture, the last few pictures start to throw other ads at you. **** you even had an ad that I had to use the task manager to get it off my screen. Come on Yahoo SMARTEN UP these sponsored ads are really low grade and insulting.
