Your computer has been locked! Virus

Also Known As: Your computer has been locked Ransomware
Damage level: Severe

What is Your computer has been locked?

This message locks users' computers, demanding payment of a $300 fine using MoneyPak. This is a scam, a ransomware infection created by cyber criminals and targeting PC users from the United States. This fake message states that the computer user's screen was locked due to downloading and distributing illegal content (child pornography).

Do not believe these statements - they are fake. Cyber criminals who have developed this deceptive message (ransomware), hope that computer users will fall for their trickery and pay the bogus fine. Neither the "Department of Justice" nor the "U.S. Department of Homeland Security" are connected with this message.

Cyber criminals responsible for releasing this scam exploit the names and graphics of these organizations.

Your computer has been locked! MoneyPak scam

In fact, no international authorities or organizations use desktop-locking messages to collect fines for any law violations. Paying the $300 fine demanded by this message is equivalent to sending your money to cyber criminals.

This particular virus (ransomware) originates from a family of screen lockers called Kovter and is just one of many targeting PC users from the United States. Other known ransomware targeting computer users from the USA, exploits the names of the Department of Justice, FBI Cybercrime Division, and many others.

As well as blocking your computer screen, the "Your computer has been locked!" virus  also scans computer users' Internet browsing history in order to make the deceptive message appear authentic.

The browsing history scan detects any recently-visited pornographic websites, and if such entries are found, are displayed in the "Source or intermediary sites" section of this ransomware infection. If no pornographic websites are detected, this ransomware displays porn.com as being found in "Source or intermediary sites".

A common source of ransomware infections such as these are exploit kits, which exploit security vulnerabilities detected on users' computers and then execute malicious code. Protect your computer by using antivirus and anti-spyware software, and if your PC is already infected, use the removal guide provided to eliminate this scam.
