Fefg Virus Removal Guide (+Decrypt .fefg files)

Fefg – Ransomware

Fefg is a malicious software application functioning as common ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.

Fefg was developed for the sole function to encrypt all popular file types. Logically, as soon as the encryption is effectively accomplished, the users are unable to get access to them. Fefg ransomware adds its own “.fefg” to all the encrypted files. For example, the file “price_list.xls”, when modified by Fefg, will be titled as “price_list.xls.fefg”. As soon as the encryption is accomplished, Fefg puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by text file requesting for the random os extremely similar to the notices offered by other ransomware threats coming from the DJVU family. The caution basically shows that the information has been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.

The approach to encrypt the files utilized by Fefg is not entirely researched. Nevertheless, there is no doubt that each computer owner may be provided an unique decryption key, which is absolutely special. It is extremely hard to recuperate the data without the proper type in place.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Fefg virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have actually introduced the Fefg virus into the world wide web. In order to acquire the key and restore the important information, the users are told to connect with the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise says that the people must contact the Fefg authors within 72 hours upon the moment of the data file encryption. The alert indicates that by doing so the people will acquire a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no warranty that these online criminals will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom typically does not lead to an effective recovery. So, the users might simply lose their money for absolutely nothing.

Likewise, we advise you not to contact the frauds as they instruct. Do not transfer cash into their wallets. There are no applications that could break the Fefg ransomware or bring back the data for free. Therefore, the only appropriate choice is to restore the data from possible backups (if offered).
