What is embedded advertising?

Why am I getting GRAPHIC porno advertisements embedded in my Yahoo mail? First time in eight years.?

• Today when I opened an email from a longtime contact there was a flashing Yahoo!Advertisement embedded in the email for "Camazon". The photo was graphic showing a woman and two men in a sexual position. When I say graphic, I do mean GRAPHIC. I'm not a prude but this is soooo in appropriate for an email service that is used by families and children. We experimented and sent several more emails back and forth and the "Camazon" advertising was embedded in each email. I will block Yahoo entirely from all computers in my home if this is not a random incident.

  This could be one of many things but i would say the most likely cause is a virus of some sort I have had this happen on my personal computer there are viruses that use your ip address to put you city name on the add you get pop ups and certain viruses can even change advertisements around. if you want you can go tho this website and run there free scan i use this when my own virus scanners don't find anything http://housecall65.trendmicro.com/ and if that fails go to http://www.download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html?part=dl-10804572&subj=dl&tag=button and get Malawarebytes Anti malaware this will clean you computer of viruses and you should not have this problem anymore.
