Why is random sound playing in the background of my computer?

[Alexaundria]

This is going to sound really weird but for some reason the movie My Best Friends Wedding keeps playing in the background of my computer. Actually it just plays the sound from the movie and I don't know where it is coming from. It has happened twice now and once I close my browser it goes away but nothing I am looking at could be playing it. For example the first time it happened I was on Facebook and I heard the sound from the movie. I don't know whats going on, could it be a virus of something?

If you are using google chrome, then it is probably an advertisement that you do not see. Try browsing with a different browser and see if the problem persists. Or, download the adblock extension for google chrome (that is if you were using google chrome). If this doesn't work, then I suggest running an anti virus, if you don't have one, download avast anti virus from http://www.download.com
