Ransom:Win32/Tobfy!mp3
Aliases: Trojan.Win32.Tobfy (Ikarus)
Summary
Windows Defender detects and removes this threat.
This threat is an audio file (MP3) used by some variants of the Ransom:Win32/Tobfy family of ransomware trojans, such as Ransom:Win32/Tobfy.L and Ransom:Win32/Tobfy.G.
The audio file contains a fake FBI warning message that says your computer is blocked for "violation of federal law". The message is played repeatedly and cannot be stopped.
If your computer is infected with this file, then it is likely you are also infected with other ransomware components, such as Ransom:HTML/Genasom.D. These components may prevent access to your computer by covering your desktop with a page that also demands payment of the fine.
You can read more 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.
