Jesus f@#$%^& christ! I've just spent an entire evening trying to track down what this f***ing sound was.
Searched & sampled every single sound on my machine to try & track the f***ing thing down. With no joy, of course.
I was beginning to think my PC was infected.
I certainly don't appreciate unasked for noises from f***ing ads! Annoying & intrusive ads like that are a guaranteed way of causing me to NEVER use that company's services or products.
