Fefg

Fefg is ransomware that encrypts the files on the computers it infects. Then, the Fefg ransomware proceeds to demand a ransom payment from its victims, in order to recover those files.

If this is what has happened to you, then stick around to see what your options are of dealing with this terrible virus.

Unfortunately, there aren’t any real guarantees that you will be able to get back the encoded files. Even paying the ransom that the hackers demand won’t ensure their safe recovery. It just so happens that the criminals might not even send the decryption key necessary to reverse the virus’ effects. And if they do, that still doesn’t mean that it will work seamlessly on any or all of the files.

Therefore, it’s a good idea to first explore other means of file recovery and only if all else fails perhaps consider paying for a decryption key. But whatever you decide to do, it’s an absolute must that you first remove Fefg from your system. Failing to do so will result in the further encryption of any new data you introduce to your system, and likely also of any files that you manage to restore. There is a designated removal guide you can use for this purpose right on this page.

Fefg virus

The Fefg virus belongs to the most harmful and devastating virus category of ransomware. The effects of the Fefg virus may often not be reversed by any means.

The Fefg virus will encrypt your files

This is, unfortunately, true for many of the latest ransomware variants out there. The thing is that encryption is very tricky business and finding a decryption code for it can be incredibly difficult. Not to mention that even the decryption key that the hackers hold may not be able to reverse the encryption of this terrible virus.

The way ransomware like Fefg, Fdcv, Kruu operates only adds to the level of its harmfulness. In fact, one of its most unnerving traits is that it doesn’t set off the vast majority of security software on the market. This is because the process of encrypting files is actually a means of protecting data, and not a malicious feat. Therefore, your antivirus program may have simply allowed Fefg to slide under its radar and continue doing its dirty deed uninterrupted.

.Fefg file extension

Victims will notice that all of their encrypted files end with the .Fefg file extension. The .Fefg file extension is what signals that a file has been affected by the virus.

Essentially, it is also part of what makes certain that a certain file won’t be opened by any other existing software that you may use.

As you will see in our tips on how you might be able to get your data back, it all boils down to two main possibilities. You can either try to have the decryption reversed like with the help of a special decryptor tool. Or you can try and get a hold of copies of the locked files. We will show you how you can try and do that from system backups, but if you have copies stored on a separate drive or cloud – you are of course welcome to use those.

Remove Fefg Ransomware


Step1

As a first step, please save this page’s removal guide as a bookmark in your browser so that you won’t have to seek for the Fefg instructions every time you restart your computer.

If your computer has been infected, the next step is to boot it into Safe Mode so that you can check what programs and apps are running in the background. After the reboot, click on the bookmark that you’ve saved and move to the instructions in step two.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

*Fefg is a variant of Stop/DJVU. Source of claim SH can remove it.

In the second step, you need to open the Task Manager, (press the CTRL+SHIFT+ESC keys simultaneously) and then carefully look for processes with strange names or processes that use a lot of resources on the Processes tab. Right-click on any suspicious process and select Open File Location from the pop-up menu to view its files.

Next, check the files connected with that process to determine if there is any malicious code. Below is a link to a free virus scanner that you can use to speed up things.

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    You may need to end the suspicious process in Task Manager by right-clicking on it and choosing End Process before deleting the files that the scanner has flagged as harmful.

    An attacker may alter the Hosts file when a machine is infected. As a consequence, the next step is to manually search for possibly problematic IP addresses in the “Localhost” part of the file (like those on the image below). It is possible to access the hosts file on your computer by hitting both of these keys together: Windows key R and pasting the command below in the Run box:

    notepad %windir%/system32/Drivers/etc/hosts

    After that press Enter from the keyboard and look for any strange IP addresses in the Localhost section of the file. If you see anything suspicious, please make a comment in the comments box given below and let us know. If we discover that the IP addresses you’ve published are harmful, we’ll get back to you with suggestions on what you should do.

    Next, search for “msconfig” by typing it in the Windows Search field and pressing Enter. When you do this step, you will see the System Configuration window on the screen. You may find a list of startup items under the task manager’s startup tab. Remove the checkmarks of those that you believe are part of the ransomware, and then click “OK” to save your changes. Make sure that you do not remove the checkmark from any legitimate startup items that are part of your computer’s operating system.

    In order to evade detection and remain active for an extended period of time, a rising number of malware programs stealthily enter dangerous entries into the system’s registry. Therefore, to uninstall Fefg completely, you need to open the Registry Editor to locate and delete any Fefg-related files that may have been added there without your knowledge. You can open the Registry Editor by entering regedit in the Windows search bar and clicking Enter. 

    Once the Registry Editor appears on your screen, you may look for files that may be related to the ransomware by hitting CTRL and F at the same time. This will open a Find box where you can type the name of the threat. To start looking for the ransomware, click the Find Next button. Any files that appear in the search results should be carefully deleted. 

    Attention! Manual removal of malware-related registry files may result in eliminating non-malware files by mistake, thus it’s important to be aware of this risk before attempting to do so. An anti-virus program is your best bet when it comes to security, since it eliminates potentially hazardous apps and dangerous registry entries without affecting essential system files.

    The following five system location may also contain malicious ransomware-related files. Because of this, you should type each of the search terms mentioned below into the Windows search bar and click Enter to open them:

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Search for files that could be dangerous, but don’t make any changes or deletions if you are not sure about them. All temporary files in your computer’s Temp directory may be deleted by holding down the CTRL and A buttons on your keyboard and then hitting the Del key.

    Step5

    How to Decrypt Fefg files

    Data that has been encrypted by ransomware may be difficult to retrieve for non-experts. The decryption procedures that may be utilized to recover the data vary based on the variant of ransomware that was used to encrypt it, thus complicating the recovery situation. The file extensions attached to the encrypted data may be used to identify between various ransomware variants.

    In order to begin the process of data recovery, you must first do a full computer scan using a professional virus removal tool (like the one offered on our website). After the system has been scanned for viruses, it is safe to explore the different file recovery solutions that are available.

    Next Djvu Ransomware

    STOP Djvu ransomware is a new variant of Djvu ransomware that has been discovered, according to security researchers. These newly encrypted files have the suffix .Fefg appended to their names. If you have been infected by this threat, you may be able to retrieve your encrypted data using a decryptor like the one available at

    https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu

    STOPDjvu.exe program needs to be downloaded on your computer before you can begin decryption of the files. Right-click on the downloaded file and choose “Run as Administrator” and then confirm with Yes. Check the license agreement and any instructions that come with it before using it. Remember, however, that this program cannot decode data encrypted with unknown offline keys or with online encryption.

    Anti-virus software on our website may help you if you run into problems with removing the Fefg ransomware. You can also use our free online virus scanner to check any suspicious files.
