Recently I was by annoyed by a sound from a male that speaks “Congratulations, you won”, which kinda freaked me out when I am alone in midnight. The sound is automatically played every few minutes. Amazingly, I can even hear the sound when my Mac is idling in login screen.
So immediately I thought there is a popup ad but I can’t find any. At last, I found the culprit, it’s from a flash advertisement in YouTube. Can you imagine that? Here’s a screenshot of it, notice the pink box.
Anyway, I never trusted these kind of advertisement because I believe there’s no such thing as a free lunch in this world.
If you are using Mozilla Firefox and wanted to block the advertisements, you might want to check out Adblock Plus.
