Nqsq Virus Removal Guide (+Decrypt .nqsq files)

Nqsq – General Info

Nqsq is a harmful software working as typical ransomware. Michael Gillespie, the popular malware researcher, very first found this new name in the DJVU ransomware family.

Nqsq was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Nqsq virus adds its own “.nqsq” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Nqsq, will be titled as “price_list.xls.nqsq”. As soon as the encryption is accomplished, Nqsq puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.

The message specified by document requesting the random os very comparable to the notices given by other ransomware hazards belonging to the DJVU family. The warning generally indicates that the data has been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is definitely real.

The approach to secure the files used by Nqsq is not completely investigated. However, there is no doubt that each computer owner may be provided an unique decryption key, which is definitely unique. It is extremely tough to recuperate the information without the suitable 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 Nqsq ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have actually introduced the Nqsq ransomware into the world wide web. In order to obtain the key and restore the essential data, the users are informed to get in touch with the scams via email or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people ought to call the Nqsq authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so the people will acquire a 50% discount rate, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online crooks will keep their pledges, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom frequently does not result in an effective recovery. So, the users might just lose their money for absolutely nothing.

Likewise, we prompt you not to call the frauds as they advise. Do not move cash into their wallets. There are no applications that might split the Nqsq ransomware or restore the data for free. Therefore, the only correct choice is to bring back the data from possible backups (if readily available).
