Opqz Virus Removal Guide (+Decrypt .opqz files)

Opqz – General Info

Opqz is a malicious software application working as common ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Opqz was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Opqz virus includes its own “.opqz” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Opqz, will be entitled as “price_list.xls.opqz”. As soon as the encryption is achieved, Opqz puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.

The message specified by document asking for the random os really comparable to the alerts given by other ransomware risks belonging to the DJVU family. The caution generally shows that the files have been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely real.

The technique to secure the files utilized by Opqz is not entirely investigated. Nevertheless, there is no doubt that each computer owner might be provided an unique decryption key, which is definitely special. It is exceptionally hard to recuperate the data without the proper key in location.

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

message from Opqz virus

One more peculiarity of the Opqz infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have actually released the Opqz ransomware into the internet. In order to obtain the key and restore the crucial data, the users are informed to connect with the scams by means of email or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people should contact the Opqz authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so the people will get a 50% discount, therefore, the ransom amount 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 assurance that these online crooks will keep their promises, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom often does not lead to a successful healing. So, the users might simply lose their money for absolutely nothing.

Similarly, we urge you not to contact the frauds as they instruct. Do not move money into their wallets. There are no applications that might split the Opqz ransomware or bring back the information for free. For that reason, the only appropriate decision is to bring back the data from possible backups (if offered).
