Aaaaaaaargh -- I have it too! It's some form of PCAdvisor nonsense. Have searched, but nothing seems to turn it off on the advert -- sorted it temporarily by muting the PC, but it's not a good enough solution.!!!!
With the last 3 adverts I mailed them informing them that due to their intrusive advertising I would never consider using them now or in the future, they replied, eventually 2 months later, saying that they took all complaints seriously, I don't think they take any notice at all.
I would agree, after the first time when I nearly had a toilet break, (I was enjoying the gentle Hum of my coooling fans and forgot the speakers were turned up from earlier) I got the Idea about what the ad was trying to say by the 2nd time, the 3rd time I was getting bored with it, and now it really is starting to well scince we can no longer use creative punctuation instead of expletives you will just have to imagine.
for now I guess I'll just have to mute the speakers as per imarcus.
