Random sounds and commercials.

Lately, as soon as I get access to the internet, random music and commercials start playing through my headphones even if I have no programs at all running.

I found out this is the sound, but how do I find the souce of it so I can find out what's causing it?
The text in the red box translates to "Name not available"
