Npsg Ransomware

Npsg Ransomware might turn your life upside down as the malicious application leaves program data unaffected, but encrypts all data considered to be private, such as documents or photos with a secure encryption algorithm. Coincidentally, files affected by this malicious application might become unreadable, and if a victim does not have backup copies to replace enciphered files, he might lose them forever. It is possible to decrypt files with special decryption software, but hackers behind the malware demand paying a ransom in exchange for it. Needless to say that there are no guarantees that cybercriminals would keep up with their promises. Thus, we advise not to pay the ransom if you do not want to risk losing your money for nothing. To learn more about Npsg Ransomware and its removal, we recommend reading our full article as well as checking the instructions placed below it.

It is best to begin by explaining how users could come across Npsg Ransomware. Our researchers say that there could be a few scenarios. For example, targeted victims could receive emails from unknown senders or people pretending to work for reputable companies. Such messages could claim that the file attached to them is important or interesting and that you should open it right away. Whatever the reason they might give, you should never rush. Instead, you should scan the attached data with a reliable antimalware tool that could determine whether it is malicious or not.

Another scenario is that victims could download Npsg Ransomware’s installers unknowingly. As you see, hackers could make them look like software installers, system updates, documents, or other files that would not raise suspicion. Usually, users download malicious installers while visiting unreliable file-sharing websites or interacting with questionable advertisements. Thus, you should keep away from untrustworthy sites or ads too, if you do not want to receive ransomware or other harmful applications in the future.

Upon entering a system, Npsg Ransomware should create randomly named folders in the %LOCALAPPDATA% directory, where it should place its malicious data. In addition, the malware might create a scheduled task or a Registry entry that would ensure its automatic relaunch after the infected device restarts. Then, the malicious application should start encrypting files that could be of value, for example, photos, various documents, archives, and so on. Each file that gets encrypted should be marked with the .npsg extension, for instance, flower.jpg.npsg.

Soon after Npsg Ransomware encrypts its targeted files, the malware should drop a text file titled _readme.txt. This document should provide a ransom note written by the malicious application’s developers. At first, it should explain that your files were encrypted and that they can only be restored with special decryption software. Then, the note should claim that hackers behind the malware have the needed decryptor and could provide it if you pay a ransom.

To convince you to put up with their demands, Npsg Ransomware’s creators could promise to decrypt a couple of files free of charge as well as give you a 50 percent discount if you contact them within 72 hours after seeing the ransom note. Of course, we do not recommend doing it because whatever the cybercriminals could promise, it does not mean that they will go through with it. They might not bother sending the promised decryption software. After all, what is there to stop them from taking the money after it reaches their account?

If getting scammed is not something you want to experience and you do not want to risk it happening, we advise against paying the ransom. Also, our researchers recommend erasing Npsg Ransomware because it might still pose a threat to your future data. If you want to know how to remove the malware manually, you could follow the instructions placed below. On the other hand, if you find the task too complicated, we encourage you to delete Npsg Ransomware with a reliable antimalware tool of your choice. Lastly, if you have any questions, you should know that there is a comments section below where you could leave us a message.
