Dear Brainking support team, Since a few days, perhaps a week or so, I've noticed that from time to time, when I click on a piece to play, a pop up raises inviting me to install "systemdoctor" on my computer. Such an ad generated by Brainking is not nice. I assume many users will think it's a system message and will then click on it. I think Brainking should be careful on these kind of things or the image of this site will be quickly fall down. (sorry if my english is not perfect)
