Npsg Virus Removal Guide (+Decrypt .npsg files)

Npsg Virus Ransomware

Npsg is a malicious software functioning as common ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Npsg was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the file encryption is successfully accomplished, the users are not able to get access to them. Npsg ransomware includes its own “.npsg” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Npsg, will be entitled as “price_list.xls.npsg”. As soon as the file encryption is accomplished, Npsg puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by _readme.txt requesting for the random os really similar to the alerts given by other ransomware hazards coming from the DJVU family. The warning generally indicates that the information has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely true.

The method to secure the files utilized by Npsg is not completely researched. Nevertheless, there is no doubt that each computer owner might be issued a special decryption key, which is absolutely unique. It is exceptionally difficult to recover the data without the appropriate type in location.

“Don’t worry, you can return all your files!”, from text file message:

Don't worry, you can return all your files! virus

One more peculiarity of the Npsg ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have launched the Npsg virus into the web. In order to get the key and bring back the crucial data, the users are told to contact the frauds via email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals need to contact the Npsg authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so the people will obtain a 50% discount rate, for that reason, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no warranty that these online scoundrels will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom typically does not lead to an effective healing. So, the users may merely lose their money for nothing.

Likewise, we advise you not to contact the frauds as they advise. Do not transfer money into their wallets. There are no applications that could crack the Npsg virus or restore the data for free. Therefore, the only right choice is to restore the data from possible backups (if available).
