Why does my computer randomly play advertisements with no prompting?
At random times our computer will just play an advertisement. We could be sitting in the same room watching TV and all of a sudden our computer is talking to us. We could be tucked in bed and our computer starts talking to us. I could be typing this description and an advertisement will randomly play.

Is it popping up in front of what you're doing when you're working on the computer, or is this playing in the background? A website in an inactive (background) tab could be reloading itself at certain intervals... Does this occur even if Firefox is completely closed?
Well, some programs have viruses that have random ad popups. I say, look through your programs, and if there isn't one that you remember downloading, please uninstall it. If this doesn't work, I say, download Adblock Plus.
Next time, please include the kinds of advertisements.
