How to restore files locked by Fefg ransomware?


Issue: How to restore files locked by Fefg ransomware?

Hello. Data on my computer is suddenly locked and I cannot see any of the contents. I need to get rid of this Fefg ransomware because I have no other way to recover files. I don't want to pay, so are there any solutions besides that?

Solved Answer

The infection that locks files directly infiltrates the machine before it displays any of these symptoms. The Fefg ransomware virus can infiltrate the machine and run in the background before it uses the encryption[1] algorithm and triggers the damage to documents, images, audio, and video files directly.

It is, however, common for the cryptovirus to start with data encryption right after the infiltration. It can be loaded from the email attachment and malicious file from there, so once the file is downloaded on the computer and malicious macros[2] get launched, the payload triggers the encoding procedure.

These are one of the most dangerous threats out there developed by cybercriminals that are financially motivated and only care for your money. Those affected files, damaged machines, and losses of the data or money are not the things that virus developers would care about. Try to stop the active Fefg file virus and move on with options for file and system repair.

1. Terminate the virus

Cyber infections need to be properly removed from the machine because ransomware can be persistent and that is because of the additional malware that the ransomware can drop on the system. Trojans and worms, and other silent infections can run in the background without causing any symptoms.

These unnoticed processes cause issues with the machine, performance, and even speed of the computer. Fefg ransomware can lead to disabled anti-malware tools and security program problems because it tries to ensure persistence. However, the detection rates[3] show that many antivirus solutions can help with the removal process.

The infection can be detected and indicated as malicious, and potentially dangerous once the system scan runs the check for virus files in various parts of the machine. Fefg file virus can leave various files and processes hidden, so proper antivirus tools find and terminate them automatically. You cannot find the app and remove it as any ordinary PUP. You need to stop the ransomware before any of the file recovery procedures.

2. Decrypt the locked data

The decryption of this Fefg ransomware virus would be the best option, but there are no tools for this because the threat is coming from a powerful virus family – Djvu virus. This particular variant is one of many recently released versions that cannot be restored easily due to advanced methods used during the infection process.

Threat relies on online ID formation, and this process means that every affected device receives a unique key, and this is the piece required during the decryption process. Victims need to get it to restore files. There is no other way to obtain those keys but to pay Fefg ransomware creators or disrupt operations of the infection fully.

Offline IDs are unique for the version of the virus only, so such a solution could help many victims. It is rare, but connections fail, and the following tool can determine if your files can be restored or not. Run a check to see if this can happen.

  • Download the app on official Emsisoft website.
  • Once decrypt_STOPDjvu.exe shows up – click it.
  • Follow the steps on the screen.
  • The tool should locate the affected folders.
  • You can also do it by pressing Add folder at the bottom.
    Decryption tool
  • Press Decrypt.
    Emsisoft decrypt
  • There are particular results that can occur indicating if the decryption is possible.

From here, there are three available outcomes:

  1. Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
  2. Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
  3. This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.
