Opqz Ransomware

Do you have $490 laying around? If you do, Opqz Ransomware wants it all. This malicious infection was created with the sole goal of taking money away from unguarded and gullible Windows users. To achieve their goals, cybercriminals have enabled the infection to encrypt personal files after invading an operating system. Once files are encrypted, their owners cannot read them, and that is when the attackers present a message, according to which, a special decryption key can be provided to them after they pay the demanded ransom. The problem is that even if you have enough to cover the sum, you will not obtain a decryptor. Cybercriminals can make any promise just to reach their goals, and in this scenario, they are promising a decryption tool to make money illegally. Hopefully, you have not wasted your money yet, but in any case, you need to remove Opqz Ransomware. We are here to help you delete this malware as quickly as possible.

STOP Ransomware is the predecessor of Opqz Ransomware, as well as Lezp Ransomware, Mpaj Ransomware, Ooss Ransomware, and hundreds of other infections, all of which are clones of one another. According to our researchers, the victims of any of these threats are most likely to face them when they interact with misleading spam emails or downloaders available on unreliable file-sharing websites. The point is to execute Opqz Ransomware without alerting the victim, and so you can expect to see disguises and clever messages. Unfortunately, ransomware is spreading like wildfire across the world, and we keep seeing new threats or new variants of these threats emerging daily. That means that Windows users continue to be careless. Note that if you delete spam emails and emails from unknown senders, and if you only download files from reputable sources, your chances of facing ransomware or other kinds of malware become much smaller. Of course, even if you are cautious, you could be fooled, which is why besides practicing caution you also need reliable security software to guard your operating system.

If Opqz Ransomware managed to slither in, your personal files are likely to be encrypted already. This malware does not waste any time. Once files are encrypted, you should see the “.opqz” extension attached to their names. For example, a file called “birthday.jpg” is changed to “birthday.jpg.opqz” after encryption. This allows you to see which files were encrypted, and so you do not need to try opening them. You will not succeed. There is a tool called ‘STOP Decryptor,’ which was created by researchers of the STOP Ransomware family. The tool is free, but it only encrypts files that were locked using an offline key, and it is not always able to decrypt the files corrupted by new variants immediately. Obviously, if you need a free decryptor, this is the one you should look into. Beware of fake decryptors offered by schemers. You do not need a decryptor if you have copies of your personal files stored online or on external hard drives. If you do, you are in the best position imaginable, and once you delete Opqz Ransomware, you can move on to replacing the corrupted files with copies.

If you contact the attackers ( and pay the ransom of $490, you will not get the decryptor, but the attackers will learn your email address – if they did not know it already – and they will be able to terrorize and scam you in the future. That is something to beware of. In any case, whether you can decrypt or replace your files, you have to delete Opqz Ransomware, and we strongly recommend leaving this task to legitimate anti-malware software. The moment you install it, your operating system will gain reliable protection, and all active threats will be removed automatically. Remember that new ransomware threats emerge daily, and there are other kinds of malware too. If you want to have your system, your files, and your virtual privacy guarded, you should install anti-malware software.
