I have an odd problem with my computer - I hear voices through it 

As I type now, I hear Barak Obama doing a speach on Iraq, yesterday I had a womens make-up channel, selling second hand cars, a cooking programme, then a natural history programme on lizards.
There are now two voices coming through, Barak and another woman, then the woman stops and music starts. If I shut Internet Explorer it carries on until I unplug the internet connection.
Now another woman author is discussing her book.
Now music again, over the voices.
Now another cooking programme.
All american voices.
My usual computer guy has never come across this before.
Any help would be greatly appreciated
