Opqz is a ransomware-based virus program that is used for blackmail purposes. The criminal creators of Opqz set it to encrypt user files so that they can later demand a ransom payment for the decryption key.


The Opqz virus will encrypt your files and leave a message in a _readme.txt file.

Opqz can encrypt all types of digital data that is stored on the infected computer. As soon as your machine has been compromised, the virus may start searching for text documents, pictures, videos, audio files, databases, and other common types of data with the intention to encode them one by one. The result of the ransomware’s attack is that you will be left with a bunch of completely unrecognizable pieces of data, which are present on the drive but cannot be used for anything. The file extension of the targeted files may also be replaced with a suffix that is odd and unreadable by any software in the system.

What is typical for the representatives of the ransomware category of malware is that they operate in stealth only during the file encryption process. After this process finishes and the desired data becomes inaccessible, the virus generates a notification that serves to inform the victims that their files have been encrypted and a ransom is demanded for their decryption. The notification of Opqz normally provides instructions about how to transfer the ransom money to a given cryptocurrency wallet. In exchange for the money, the hackers behind the ransomware promise to send a decryption key. This decryption key is all you need to reverse the applied encryption and to access your data again. We must inform you, though, that paying the ransom is not the wisest course of action. In fact, this is the riskiest one because you can never be sure that once you pay the money, you will receive a decryption key from the hackers. On the other hand, there are methods that may help you recover your files for free. In the removal guide that you will find below, we have mentioned several of them. If you want to give them a try, however, it is important to first remove the ransomware from the system in order to prevent further file encryption.

The Opqz virus

The Opqz virus is an infection that does not corrupt digital files but is still dreaded because it restricts access to them. The way the Opqz virus causes harm is by applying encryption to valuable user information and keeping it inaccessible until a ransom is paid for the decryption key.

A ransomware threat like this one can successfully remain under the radar of the majority of conventional antivirus programs since it doesn’t cause actual system damage or corruption that can trigger the security software’s virus definitions. That’s why the most reliable way to secure your data against such infections is by making file backups and keeping them on remote disks or cloud storage.

The Opqz file distribution

The Opqz file distribution is an arsenal of malware delivery tactics that are used to infect as many online users as possible with the ransomware. Cybercriminals rely mostly on malvertisements when it comes to injecting the Opqz file into more computers but people can get infected also by clicking on misleading links or illegal websites. Regardless of the method of infection, the ransomware should be carefully removed from the system in you want to be able to use your computer and save data on it without it being encrypted.

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


Hold the Start Key and R copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.
