A quick search indicates that this is likely a tech-support scam popup message, and not a virus. These popups can temporarily lock up your browser, but nothing is actually installed on your computer. Usually force-closing your browser via task manager or rebooting your computer will clear these up. 

 

If you are still getting the popup after rebooting your computer, please Submit a Support Ticket and we can help you clear that up.
