YES! I got the warning screen (which is NOT legit) and clicked to close it and my whole computer (at work) was taken over by a screen claiming to be the FBI and asking me to pay money for pirated videos. There were misspellings, etc. I could not exit that screen even by rebooting. IT had to come up and do a reset and updated my anti-virus software. They said if you click on anything on those virus warning screens it will be a mistake! Go to task bar and close it.
