Jigsaw ransomware removal instructions
What is Jigsaw ransomware?
Jigsaw is ransomware that uses the AES algorithm to encrypt various files stored on computers. Targeted files include .jpg, .docx, .mp3, .mp4, and many others. Depending on the ransomware version, one of the following file extensions is added: ".NDGHacks", ".epic", ".HYDRA", ".paycoin", ".pennywise", ".data", .locked_by_mR_Anonymous(TZ_HACKERS), .spaß, .F*ckedByGhost, .#__EnCrYpTED_BY_dzikusssT3AM_ransomware!__#, .lockedgood, .pleaseCallQQ, .hacked.by.Snaiparul, .dat, .tedcrypt, .invaded, .black007, .F*ckED, .##___POLICJA!!!___TEN_PLIK_ZOSTA, .firstname.lastname@example.org, .choda, .booknish, .hac, .LolSec, .email-[email@example.com].koreaGame, .jes, .Bitconnect, .firstname.lastname@example.org, .paymrss, .justice, .LOCKED_BY_pablukl0cker, .CryptWalker, .F*CKMEDADDY, .##ENCRYPTED_BY_pablukl0cker##, .####CONTACT_US_pablukl0cker638yzhgr@2tor.com####, .game, .#, .pablukCRYPT, .pabluk300CrYpT!, .pabluklocker, .afc, .korea, .kill, .rat, .Crypto, .paymts, .sux, .ghost, .R3K7M9, .tax, .lost, .beep, .ice, .die, .PAY, .Contact_TarineOZA@Gmail.com, .getrekt, .lckd, .crypte, .I'WANT MONEY, .nemo-hacks.at.sigaint.org, .jey, .gefickt, .email@example.com, .paytounlock, .hush, .locked, .payrmts, .afd, .paybtcs, .fun, .kkk, .gws, or .btc. After encryption, this ransomware displays a window with a message listing the encrypted files and stating that victims can only restore them by paying a ransom. In addition, every sixty minutes, .Fun deletes a certain number of files, thus, putting victims under pressure to pay, since delays result in permanent deletion of more files.
The size of ransom is equivalent to $150 and must be paid in Bitcoins within 24 hours following infection. The ransomware window contains a 60-minute timer, which indicates time remaining until next file deletion. Initially, this ransomware deletes one file, however, after each 60-minute period has elapsed, the number of files targeted for deletion increases. In addition, when the victim restarts the computer or re-executes this ransomware, it deletes a further 1000 files. According to the message, all files will be deleted within 72 hours. As mentioned previously, this ransomware uses AES - an asymmetric encryption algorithm. Thus, public and private keys are generated during encryption. To decrypt their files, victims must supposedly purchase the private key from cyber criminals. Fortunately, MalwareHunterTeam, DemonSlay335, and Lawrence Abrams have developed a tool capable of decrypting files compromised by this ransomware (download link). Therefore, there is no need to pay the ransom. It is, however, unlikely that users will be able to restore files affected by ransomware-type viruses without the private key. In this case, you should restore your system and/or files from a backup.
Screenshot of a message encouraging users to contact the developers (firstname.lastname@example.org) of .Fun (Jigsaw) ransomware to decrypt their compromised data (you can see a picture of Billy the puppet in the background):
This ransomware is very similar to hundreds of other viruses that also encrypt files using an asymmetric encryption including, for example, Locky, Cerber, Locker, CTB-Locker, and CryptoWall. All infiltrate systems, encrypt files, and make ransom demands. The main difference is the type of algorithm used and size of ransom. There is a high probability that your files will not be decrypted even if you pay the ransom. Therefore, never attempt to contact cyber criminals or pay any ransom - this will merely support their malicious businesses. Most ransomware-type malware is distributed via fake software updates, trojans, malicious email attachments, and peer to peer (P2P) networks such as Torrent. Therefore, keep your installed software up-to-date and use a legitimate anti-virus/anti-spyware suite. Additionally, be very cautious when downloading files sent from suspicious/unrecognized emails and third party sources.

An updated variant of this ransomware (calls itself variant 4.6):
Ransom demand message:
Your computer files have been encrypted. Your photos, videos, documents, etc…
But, don’t worry! I have not deleted them, yet.
You have 24 hours to pay 150 USD in Bitcoins to get the decryption key.
Every hour files will be deleted. Increasing in amount every time.
After 72 hours all that are left will be deleted.
If you do not have bitcoins Google the website localbitcoins.
Purchase 150 American Dollars worth of Bitcoins or .4 BTC. The system will accept either one.
Send to the Bitcoins address specified.
Within two minutes of receiving your payments your computer will receive the decryption key and return to normal.
Try anything funny and the computer has several safety measures to delete your files.
As soon as the payment is received the crypt files will be returned to normal.
Another variant of Jigsaw ransomware - uses a different ransom message background (flowers) and text:
Text presented in this variant of Jigsaw ransomware:
I want to play a game with you. Let me explain the rules: All your files are being deleted. Your photos, videos, documents, etc... But, don't worry! It will only happen if you don't comply. However I've already encrypted your personal files, so you cannot access them. Every hour I select some of them to delete permanently, therefore I won't be able to access them, either. Are you familiar with the concept of exponential growth? Let me help you out. It starts out slowly then increases rapidly. During the first 24 hour you will only lose a few files, the second day a few hundred, the third day a few thousand, and so on. If you turn off your computer or try to close me, when I start next time you will get 1000 files deleted as a punishment. Yes you will want me to start next time, since I am the only one that is capable to decrypt your personal data for you. Now, let's start and enjoy our little game together!

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of .Fun are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and Malwarebytes Anti-Ransomware, which artificially implant group policy objects into the registry to block rogue programs such as .Fun ransomware.)
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
