Facebook users are being warned of a scam to cut and paste info from a message into your URL... If you do this you will be done all right.. done for is more like it.. Re-install Windows if you have fallen for this...
Generally speaking NEVER act upon a message asking you to paste anything into your browsers URL or click on any URL without using something like No Script for FireFox and Not Script for Chrome to block that bad script shtuff that will infect you.
Remember.. Your behavior will protect you, not your Anti-Virus software!
