Not sure what you're talking about.
but I've used RealPlayer as my player of choice and downloader of music and video for over 11 years. Not one, I repea,t NOT ONCE, has there ever been an advertisement that appeared on this player. My downloads are checked automatically with TrendMicro and never once, ever, has an item been downloaded by RealPlayer that containded any type of malware, including spyware. I'm thinking that you may have had some of these problems occur and erroneously blamed RealPlayer but I have never had a bit of problem with it. That is why I use it and defend it.
