Yjqs Virus Removal Guide (+Decrypt .yjqs files)

Yjqs Virus – Details

Yjqs is a malicious software functioning as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Yjqs was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively accomplished, the users are not able to get access to them. Yjqs virus adds its own “.yjqs” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Yjqs, will be entitled as “price_list.xls.yjqs”. As soon as the encryption is accomplished, Yjqs puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The message specified by text file asking for the random os very comparable to the notifications offered by other ransomware threats coming from the DJVU family. The caution essentially indicates that the information has been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely true.

The technique to secure the files utilized by Yjqs is not totally researched. However, there is no doubt that each computer owner may be issued an unique decryption key, which is definitely distinct. It is extremely hard to recuperate the information without the proper type in location.

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

One more peculiarity of the Yjqs infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have actually introduced the Yjqs infection into the world wide web. In order to obtain the key and restore the important information, the users are told to contact the scams by means of email or by telegram and to pay the ransom in the amount of $980.

The message also says that the people need to get in touch with the Yjqs authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so the people will obtain a 50% discount rate, for that reason, the ransom amount drops down to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no guarantee that these online crooks will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. For this reason, paying ransom typically does not result in a successful healing. So, the users may just lose their money for absolutely nothing.

For that reason, the only correct choice is to bring back the data from possible backups (if readily available).
