Summary
Windows Defender detects and removes this threat.
This threat stops you from loading Windows 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 tries to scare you into paying a fine or texting a premium-charge phone number to unlock your PC.
