Okay so I have been surfing around the internet like I normally do and for some reason there is a sound effect of a cat's meow coming up on my computer. It's completely random! I really want it to go away. It's rather annoying since I thought my cat was trapped somewhere the first time heard it. You should've seen me I was searching all the drawers in my desk like a fool.

Is there something more to how the sound effect got there? It doesn't happen at regular intervals. Sometimes an hour will go by w/o hearing it sometimes five minutes will go by.I haven't downloaded any programs and I don't consistently have one up except firefox. Is it a virus, spyware? Help appreciated! Thanks!
