If that screen pops up while you are working, you need to hold the power button down on the computer and shut it down improperly.
Wait a minute and turn computer back on and go to Microsoft download center and have a free full security scan run on the computer.
Follow any instructions that are prompted through Microsoft.This is a old scam, they down load a virus then charge you to remove it.
