The article will aid you to remove .Jaff File Virus effectively. Follow the .Jaff File Virus removal instructions at the end.
The .Jaff file virus is ransomware that encrypts data on your computer if it gets infected. Rumors about it being connected to the infamous Locky ransomware have dispersed after malware researchers have denied that being true. .Jaff will be the newly-appended extension to all files after they get encrypted. What is notable about the Jaff cryptovirus is that it copies some things from Locky like the payment page design, the way it spreads etc. Read on to see how you could try to potentially restore your files.

.Jaff File Virus – Update
.Jaff File Virus – Distribution Ways
Jaff ransomware not only utilizes the same distribution method used by the latest Locky virus, but it even surpasses it. That could be due to the probability of using another method for distribution alongside the ones it copies. Adding more to it, Jaff also copies the obfuscation (a tactic for malware to hide itself better) from the same source (Locky). Down here the distribution, extraction and infection ways of the .Jaff file virus will be explained.
Spam e-mail campaigns are in play, spreading millions of emails, which have PDF files attached to them.
Opening the PDF file will show the following:
Inside the PDF, you will see that there is an embedded .docm file, which you will be kindly asked to open up. This is how that document file looks from the inside if you open it up:
Once loaded, you will be asked to click on “Enable Editing” and right after that on “Enable Content”. From then on a macro script is loaded that will download the malicious executable for the .Jaff File Virus. The macro commands is detected to download the virus from one of the following URL locations:

Jaff ransomware could also be distributing its payload via social media networks and file-sharing sites. Refrain from opening files after downloaded them, especially if they come from places such as suspicious emails and links from an unknown source. Beforehand, you should scan the files with a security program, at the very least.
.Jaff File Virus – Technical Expertise
.Jaff file virus is ransomware, dubbed after the extension it places on files, after it encrypts them. Many have argued that it is a variant of the notorious Locky ransomware virus (.Loptr), due to the similarities between them. However, that has been proven otherwise by malware researchers who investigated the matter and concluded that their malicious code is different.
The .Jaff file virus copies Locky in more than one way, and uses that as a complementary scare tactic. Jaff is written on the “C” programming language, and its code is far less sophisticated than Locky. Still, that doesn’t exclude the possibility of the two ransomware viruses to share the same author. According to Proofpoint researchers, the malware spam campaigns for both viruses are currently spread via the Dridex Trojan, which itself is spread by the Necurs botnet. That’s some food for thought.
The .Jaff file virus makes entries in the Windows Registry to achieve a higher level of persistence, and even could launch and repress processes inside the Windows Operating System. Some of these entries are designed in a way that will start the virus automatically with every launch of Windows. A registry entry used by Jaff is:
→HKCU\Control Panel\Desktop\Wallpaper “C:\ProgramData\Rondo\WallpapeR.bmp”
The ransom note will be displayed after the encryption process finishes. The ransom note will be put inside three files, which are:
- ReadMe.bmp
- ReadMe.html
- ReadMe.txt
All three files will have almost exactly the same contents.
Here is how the note looks like from the ReadMe.html message:
From the instructions given on that ransom note, you will be pointed out to the TOR payment page of the .Jaff file virus:
The Tor page will have the same design as the one of Locky, but with some minor difference.
The payment page states the following:
jaff decryptor system™
We present a special software – jaff decryptor™ – Recovery all files

Apparently the .Jaff File Virus demands you to pay 1.82 Bitcoin, which equals to 3.382 US dollars at the moment of writing this article. Despite that, you should NOT under any circumstances pay the ransom of the cybercriminals. Nobody can guarantee that you will get your files restored from paying, nor that you won’t get your computer infected again in the future. Providing money to these criminals will motivate them further in the creation of more ransomware viruses.

Each one of the files that gets encrypted will receive the same extension appended to them, and that is the .Jaff extension. The encryption algorithms which are utilized by the ransomware are believed to be AES and RSA.
The Jaff cryptovirus could be set to erase the Shadow Volume Copies from the Windows operating system by using the following command:
→vssadmin.exe delete shadows /all /Quiet
If the command above is executed, it will make decryption efforts harder, if you try to use a recovery method that involves the Shadow Volume Copies. Continue reading and see in what ways the potential restoration of your files could work.

Step 2: Uninstall .Jaff File Virus and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by .Jaff File Virus on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by .Jaff File Virus there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove .Jaff File Virus
Step 5: Try to Restore Files Encrypted by .Jaff File Virus.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:

4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and .Jaff File Virus aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
