Summary
Windows Defender detects and removes this threat.
This threat locks your PC and displays a full-screen message, commonly called a "lock screen". If this threat asks you to pay a fee or fine, do not pay it. The message is a fraud.
It pretends to be from the FBI or a national police force and tries to scare you into paying a fine to unlock your PC.
Typically, this threat gets on your PC when you visit a hacked webpage.
You can read more about this type on malware at the Ransom:Win32/Urausy family description or on our ransomware page.
There is no one-size-fits-all response if you have been victimized by ransomware. There is no guarantee that paying the ransom will give you access to your files.
If you've already paid, see our ransomware page for help on what to do now.
