JJWW Virus Ransomware 🔐 [.jjww Files] Remove & Decrypt Fix [Free]

What Is JJWW Virus?

jjww-ransomware-removal-decryption-sensorstechforumThis removal guide shows detailed information about JJWW ransomware, and provides removal instructions. You will also be presented with several alternative data recovery methods.

This ransomware is the latest strain of a vicious ransomware family known as STOP/Djvu. Like its predecessors, JJWW virus corrupts computer systems via several attack stages. During the attack, the ransomware encrypts files and appends the .JJWW extension to their filenames. The primary goal of the ransomware is to force you into paying a ransom fee for the alleged restoration of your encrypted data.

Unfortunately, most data locker ransomware, JJWW ransomware included, lock files with strong cipher algorithms that can be decrypted by specific tools only. However, we don’t recommend that you pay hackers the ransom as there is a real chance that you will get scammed once again. Lots of times victims who pay the ransom don’t receive the key or the decrypter. The best way to recover your files is from a previously created backup.

N.B. One of the most common questions in ransomware infections is how to decrypt the encrypted files, as is the case with the JJWW virus STOP/DJVU variant.

Unfortunately, if your files have been encrypted by ransomware, it most probably means that the battle is lost. The chances to get your files restored on your own or with the help of a company/a professional that advertises decryption capabilities are nearly non-existent. What most such companies and professionals do is buy a decryption tool from the ransomware operators, and add a markup to the ransom amount upon charging you for their decryption services. In other words, trusting anyone, other than an officially released decrypter, with the decryption of your files is utterly pointless. We will update this article once we have more information on possible decryption, even though the chances are quite slim. What you should do for now is remove the ransomware from your system, so that it doesn’t reinfect you and it doesn’t spread further. Continue reading to get to the final part of the article where we provide technical removal instructions.

JJWW Virus – More Information

JJWW is a ransomware infection that has recently been spotted in the wild. As a strain of one of the most vicious ransomware families – STOP, the threat disrupts system security and encodes personal files. In the beginning, the ransomware corrupts system settings that help it to evade detection and hide malicious files. Beware that when an infection with the ransomware occurs, some major registry keys in the Registry Editor are contaminated. The reason is that their functionalities can enable it to launch malicious files every time the infected system is started.

In terms of distribution, techniques that ransomware operators use include spam emails, email attachments, hacked web pages, and corrupted freeware installers. Since the malspam propagation technique enables hackers to spread their malicious code on a large scale it is considered to be the main one.

So, how to recognize an email that endangers the overall security of your PC and data stored on its drives? First, answer these questions:

Does the email have an attached file of common type or a link presented as a button, an image, a plain URL or another clickable form? If the answer is positive then avoid interacting with these elements. If you believe that you should view the content then scan the file / link with online malware scanners like VirusTotal. The results will provide information about the security level of the content.

All initial malicious changes performed by the ransomware aim to enable it to reach the data encryption stage. During this stage, the ransomware launches a strong cipher algorithm to encrypt personal files. All drives and folders are scanned for commonly used types of files as they are likely to store valuable user data. As a result of encryption, corrupted files receive the malicious extension .JJWW .

Unfortunately, encrypted files remain inaccessible after encryption. The malicious file extension .JJWW may appear at the end of document, music, project, database, image, video, backup, archive, and audio files. It should be noted that in order to remain unnoticed displays a fake Windows update pop-up during the encryption:

fake Windows update pop-up hides the encryption

At the end of the attack, JJWW virus drops a ransom message to extort a ransom fee from victims. In fact, the primary goal of JJWW virus is to blackmail you into paying a ransom fee to hackers. So its ransom note called _readme.txt informs that the decryption of corrupted files can be realized after you pay hackers a ransom fee ($490 – $980 in Bitcoin). Here is the full text content of this file:

How to Remove JJWW Virus

The so-called JJWW ransomware virus is a threat with a highly complex code that disrupts system security in order to encrypt personal files. Hence the infected system could be used in a secure manner again only after you remove all malicious files and objects created by the ransomware. The steps presented in the ransomware removal guide below will help you with the complete removal process. Beware that the manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide. It is also worth mentioning that personal data remains encrypted even after the complete removal of JJWW virus. Its removal only prevents it from causing further encryptions and security issues.

Step 5 from our JJWW ransomware removal guide presents alternative data recovery methods that may be efficient for the recovery of encrypted files. Beware that you should make copies of all encrypted files and save them on a flash drive for example before the beginning of the recovery process.
