Qweuirtksd ransomware is a malware that appears on the system to make your files useless

Qweuirtksd ransomware
Qweuirtksd ransomware virus is a malware that focuses on data-locking.

Qweuirtksd ransomware — malicious cryptovirus that encrypts users' data by using an AES-128 algorithm and adds a strange file extension called .qweuirtksd. First noticed at the beginning of October, this ransomware is a fairly simple crypto-extortionist which starts its encryption procedure immediately after infiltration. After the successful encoding, ransomware generates a detailed message and places the ransom note !!!ReadMeToDecrypt.txt on every folder on the device. This file contains more detailed information about the ransomware attack and states the victim has to pay $500 ransom to recover files encrypted by Qweuirtksd. While this file-locking malware can make your data inaccessible and useless, we highly recommend steering away from any contact with cybercriminals.

In most of the cases, Qweuirtksd virus affects Windows users and the main issue, besides encrypted files and a need to pay the ransom, is the fact that the malware can alter your registry, and add or remove different files to launch the threat everytime you restart your device. 

However, the main symptom of these threats is data encryption which takes a few seconds because of the powerful encryption algorithm used for this procedure. When this process is done, ransomware develops a ransom note and places the file called as !!!ReadMeToDecrypt.txt on every folder that contains the encoded data.

Qweuirtksd ransomware ransom note includes the following statements:

Attention, all your files are encrypted with the AES cbc-128 algorithm!

It’s not a virus like WannaCry and others, I hacked your computer,
The encryption key and bitcoin wallet are unique to your computer,
so you are guaranteed to be able to return your files.
But before you pay, you can make sure that I can really decrypt any of your files.
To do this, send me several encrypted files to cyrill.fedor0v@yandex.com, a maximum of 5 megabytes each, I will decrypt them and I will send you back. No more than 5 files. Do not forget to send in the letter bitcoin address 1BhHZxek7iUTm1mdrgax6yVrPzViqLhr9u from this file.
After that, pay the decryption in the amount of 500$ to the bitcoin address: 1BhHZxek7iUTm1mdrgax6yVrPzViqLhr9u
After payment, send me a letter to cyrill.fedor0v@yandex.com with payment notification.

As a bonus, I will tell you how hacked your computer is and how to protect it in the future.

The developers of Qweuirtksd ransomware have been asking the $500 ransom for unlocking encrypted files. However, as we have already said, this is not the best option if you want to get your data back. Paying the ransom cannot get your files decrypted. Even more, it may even lead to permanent money or data loss.[2] You should focus on the virus termination and then recover your files instead.

No matter that the ransom note is stating that there is no other choice to get your files back, only the ransom payment, remember that these people are cybercriminals and should not be trusted. You can always use your backups to recover files encrypted by Qweuirtksd. Besides, check alternative methods below the article if you have no extra copies of your important data.

Qweuirtksd ransomware removal can be performed with anti-malware tools like Reimage. Automatic virus elimination is recommended by cybersecurity professionals[3] because it guarantees a full elimination of your virus. In the meanwhile, manual removal requires checking all system's locations and eliminating every malware's component manually. 

However, don't waste your time and remove Qweuirtksd ransomware as soon as you spot the differences on your computer because of the malware may start additional changes on your computer. Additionally, start the data recovery process. Don't change the order of these processes because the virus can launch yet another encryption on your computer.

Ransomware can be distributed by fake emails

You should be extremely careful with spam if you want to prevent installation of ransomware. Spam email attachments have been actively used to spread this type of malware. If you are tricked by the malicious email message and download the attached file to the system, the malicious file launches ransomware's processes with the purpose of injecting it. 

Spam email campaigns can be used for various purposes, but ransomware's distribution is one of the most dangerous. Pay attention to which emails you open freely and without thinking. You may be tricked by the known company name or the subject line indicating about financial information.

Note that malicious actors masquerade their products behind safe-looking MS Word or Excel files and names like PayPal or FedEx. Do not open suspicious emails and always look for typos or grammar mistakes. Delete the email if you never used the service or at least try scanning the file before opening.

Terminate Qweuirtksd ransomware by using reputable tools

If you need to remove Qweuirtksd ransomware, we highly recommend using anti-malware software to get rid of each of its files. If you do not have reliable anti-virus, use Reimage or Malwarebytes MalwarebytesCombo Cleaner, Plumbytes Anti-MalwareMalwarebytes Malwarebytes for the job. Make sure these programs are up-to-date before a scan to have the full virus database and help you find all malicious components. If your system is infected with additional malware, a full system scan can help you eliminate it as well.

Qweuirtksd ransomware removal can be followed by the additional step which is restoring encrypted data. The easiest way to do that is using backups of encrypted files. You shouldn't start recovering your data on the system which is still infected because active ransomware encrypts any newly-added data.
