What is FBI Online Agent?

The FBI Online Agent ransomware is a computer infection that locks your screen so that you are unable to access your Windows desktop, programs, or documents until you pay a ransom. This ransomware pretends to be a program from the FBI that states that unauthorized cybercrime was being committed from your computer. It then requires you to submit a $200 MoneyPak voucher code in order to unlock the screen. It also threatens that if you do not send the payment within 48 hours your computer will be permanently locked and legal action will be taken against you. Please remember that this is a computer infection and that the FBI is not locking your computer, so please do not be worried about the messages in the lock screen. This infection is detected by a variety of anti-virus vendors using the Trojan-Ransom.Win32.Dapato, Trojan:Win32/LockScreen.CO, Trojan.Agent/Gen-Kryptik identifiers.

When you are infected with the FBI Online Agent infection when you login to Windows you will be shown a large screen that is supposedly from the FBI instead of your normal Windows desktop. The screen will state that:

FBI Online Agent has blocked your computer for security reasons.
The work of your computer has been suspended on the grounds of unauthorized cyberactivity.
To unlock your computer and to avoid other legal consequences, you are obligated to pay a release fee of $200.
Exchange your cash for a MoneyPak voucher and use your voucher code in the form below.

There will then be a form where you can submit the MoneyPak voucher code in order to unlock your screen.

As this is an infection and you are not actually in trouble with the FBI, please do not send them any MoneyPak payments. Instead, please you use the removal guide below to remove the FBI Online Agent from your computer.
