It happened to me twice, but it was coming from some other program. Once I had to just run a scan and it was fixed. The other time, well I had to reboot my whole system. It was that bad for some reason, ads kept playing and the volume wouldn't even go down. Lost a bunch of old Blockland saves that day. It taught 13 year old me to never watch research never download stuffty programs from stuffty websites and never to click the fake download buttons.
