Npsg ransomware (Free Guide) - Decryption Steps Included

Npsg virus Removal Guide

What is Npsg ransomware?

Npsg ransomware is the threat that masks its malicious processes by showing false Windows update pop-ups

Npsg ransomwareNpsg ransomware is the virus that demands victims to pay, so their files can get recovered. Unfortunately, that is the claim of cybercriminals who cannot be trusted. Npsg ransomware is the cryptovirus that interferes with various functions and system processes to keep the malware actively running on the machine. The virus hides those activities and masks the performance issues by showing a false Windows update pop-up. This is the malware that uses encryption algorithms[1] to change files and make them unopenable and useless, so there is a reason to blackmail people. Victims get ransom demanding message in the file _readme.txt that appears on the desktop and in other folders that contain encoded and marked data. Once files get the .npsg extension at the end of the original name they are no longer readable, so the victim cannot even tell what is in it. However, the recovery is not that simple because army-grade encryption algorithms are powerful.

Even though Npsg ransomware virus developers claim to offer the test decryption it is not advised to trust them. This kind offer may be a scam because criminals store some files smaller than 1GB, so they can send you an unencrypted version. Decryption previously was a great option in this Djvu/STOP ransomware family, but recent changes in the coding and methods no longer allowed to use the STOPDecrypter as a tool for file recovery. Victims that get malware developed after August 2019 have fewer options now. Nevertheless, some of the people can decrypt their data with Emsisoft's decryption tool, but that only goes for the ones with a t1 at the end of the victims' ID. Such an ending indicates that offline keys got used in the process.

Name Npsg ransomware
File marker .npsg is a random character extension appearing on the file that got encrypted. This extension goas after the original file name and file type marker, so you can at least know what data got encoded and damaged even when you cannot read the contents
Family Djvu virus
Danger This virus encrypts files and blackmails victims by claiming to have a decryption tool that they need for data recovery. It can be dangerous to even contact developers, but paying is not the option, so it may lead to lost money and permanent data loss when files cannot be recovered in any way
Distribution Pirated products deliver payload droppers or other malware that executes the ransomware. Files added on emails as attachments also can be injected with malicious macros that have the same purpose of spreading cryptovirus
Ransom note _readme.txt is the file that gets placed on the desktop and in other places where the victim can see, so the ransom demanding message reaches the person. This file is the one that has all the contact information and details about making the payment
Elimination The process can be more difficult than you think because Npsg ransomware​ removal requires attention to details and professional anti-malware tools that can do the best job of terminating this malware
System cleaning Since ransomware infiltrates the system silently it can run in the background and make various changes, that you need to reverse to get to the normal working computer. For that, we would recommend going for proper system tools like FortectIntego that might fix the affected files and virus damage for you

Npsg ransomware comes from the developers of well-known Djvu and STOP ransomware viruses. This is the 200th version already and comes after a handful of other variants that victimized many people around the globe. There was a time when many people got their files recovered and fully restored infected devices thanks to researchers.

However, that was possible due to offline keys that developers used for a long time. Since summer 2019, the encryption coding got altered and now includes online victim IDs that are generated for each person separately. Versions after that, including this most recent one – Npsg ransomware cannot be decrypted unless the virus used offline ID on your device.

The only possible way to recover files is to get data backups or a third party program that is designed to restore affected files. You need to make sure that Npsg ransomware is terminated and no longer active, so your files are safe. Ransomware can detect new files and encrypt them or encode all the files once more what makes them damaged forever, so be careful.

Also, be careful with those criminals that developed this threat because they only care for your money. This is why the encryption process and showing ransom note is the main goal of Npsg ransomware creators. The deliver the following message for victims:

Npsg ransomware virusNpsg ransomware is the file-locking threat that marks already affected data with .npsg appendix. Npsg ransomware developers want you to pay the demanded amount of $980 as soon as possible, so the ransom note is set to make you believe they are the only solution for you. However, contacting these criminals can lead to more issues regarding the safety of your privacy, identity and the general secureness of the machine.

If you decide to write them, malicious actors can convince you that there is a bigger issue and you need to pay more or infect the machine with a more severe threat than Npsg ransomware like info-stealer or a trojan. The whole money involvement is dangerous and the risk of getting the computer damaged permanently is real.

Try to ignore those scary messages and claims about the loss of your data and try to remove Npsg ransomware right away. The sooner you get to clean the machine the better, but you can still consider the decryption in the future and store some affected or malware related files on a different external device, in case researchers could release a new option in the future.

If you don't trust decryption and want to get rid of the threat to be recover affected valuables as soon as possible, get anti-malware tools or use the security tool that you already own and scan the machine. Things about Npsg ransomware removal that experts[2] want you to consider:

  • detection names shouldn't be important for you, as long as it is the threat that you need to get rid of;
  • different tools use different databases, so you may need to try a few programs until it properly works;
  • virus removal cannot restore encrypted files or affect other functions, it only cleans the traces of cryptovirus.

Npsg file-loking virusNpsg ransomware is the cryptovirus that focuses on money-demanding, so people behind the threat makes a profit.

Stay away from sharing services and pirating sites to avoid malware

It may be old news, but the internet is filled with misleading, deceptive and sometimes even dangerous content. Malicious actors create particularly infected websites where a few clicks can lead to malware infiltration. There are many types of files that can be injected with malicious code or have the payload directly embedded in data.

The most common way of distribution in this particular ransomware family is torrent sites, file-sharing services that provide pirated software[3] with additional malware material:

  • licensed versions of programs;
  • cracks;
  • game cheats.

Once the person installs such files they also get the file with ransomware payload or a direct executable file with malware on it. Such payload can be injected on document files attached to email notifications, so people skip through checking and loads the virus directly on the computer.

Terminate all files related to Npsg ransomware before going for any of the data recovery options

When dealing with Npsg ransomware virus it is important to note that encryption is not the only process that the virus runs on the infected device. Even though it affects your important files and makes data useless, you need to know that in time this threat can damage the computer permanently.

This is why you need to remove Npsg ransomware from the machine as soon as possible, until the serious damage. The best option for this would be anti-malware programs like SpyHunter 5Combo Cleaner or Malwarebytes. Antivirus engines that are based on detecting malicious programs can find various parts of the virus and delete them.

It is important for Npsg ransomware removal that you are terminating all parts of the threat and there is no possibility that encryption can be sent to occur again. To check the essential parts of the system and fix virus damage, you should run FortectIntego. After system repair, you can freely restore encrypted data from a backup.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
