Qstx Virus Removal Guide (+Decrypt .qstx files)

Qstx Virus Ransomware

Qstx is a malicious software application working as typical ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Qstx was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are not able to get access to them. Qstx virus adds its own “.qstx” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Qstx, will be entitled as “price_list.xls.qstx”. As soon as the file encryption is achieved, Qstx puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The alert specified by text file requesting the random os really similar to the alerts given by other ransomware risks coming from the DJVU family. The warning generally shows that the files have been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is absolutely true.

The approach to encrypt the files utilized by Qstx is not totally investigated. Nevertheless, there is no doubt that each computer owner may be issued an unique decryption key, which is definitely special. It is exceptionally tough to recover the information without the suitable key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Qstx virus 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 criminals who have released the Qstx infection into the world wide web. In order to acquire the key and bring back the essential information, the users are told to connect with the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals must contact the Qstx authors within 72 hours upon the moment of the information encryption. The alert shows that by doing so individuals will get a 50% discount, therefore, the ransom amount drops down to $490.

No matter what the amount of the ransom is, we highly recommend that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom often does not lead to a successful healing. So, the users might simply lose their money for nothing.

Similarly, we prompt you not to call the scams as they instruct. Do not move cash into their wallets. There are no applications that might split the Qstx ransomware or restore the information for free. Therefore, the only appropriate decision is to restore the information from possible backups (if readily available).
