Just try using another player, any but Real Player.
If pop-ups open in Real player's browser itself, there isn't really
much to worry, except dun click on anything and just close
it.
However, if an external browser opens up, be mindful that it could
be a script not related to real player's browser function and could
be harmful. scan the file in this case.
Most of this rvmb popups came from china websites because they
provides lots of movies and videos encoded with rvmb format online
for download through torrents. And their competition is real tough,
desperate to get most clicks on their own website, they do this.
Just bare with it, remember whatever video you get you are not
paying for it.
You can also look out for avi format next time instead of rvmb, a
lot safer technically.
