Bad news about the trivia quiz
It seems the quiz website I was using has been hacked. Firstly I got the fake McAfee pop up claiming to have found 5 viruses. That was easy to get rid. But then I got the full screen that you can't just close, and the constant voice saying you facebook login and banking details have been compromised, you must phone the toll free number on screen for us to unlock your computer.
It's total rubbish as I unlocked it by restarting. But I'm not risking that website again. And I done a full scan just to make sure.
