Qpss is a file-encrypting malware program that will apply encryption to some of your files, keeping them locked and not allowing you to access them. The goal of viruses like Qpss is to blackmail the attacked victims for a ransom payment that must be issued if the user wants to get their files back.

The Qpss virus file ransom note

If you are unable to open or use any of the files on your computer and a strange error message or a ransom-demanding notification note appears every time you click on them, then this could be a sign of a possible Ransomware infection. On this page, we will talk about one newly reported representative of the Ransomware category which goes under the name of Qpss and which is also the most likely reason you are currently reading this write-up. You will know that you have been infected with this piece of malware if some or most of your files cannot be opened by any program that you have on your PC. Also, a scary ransom-demanding notification may appear on your screen, stating that if you don’t pay a certain amount of money within a given deadline, you will never be able access any of your files again.

Qpss is a very problematic cryptovirus which is very difficult to remove. It has been created by anonymous cyber criminals with the idea to blackmail the web users in the above-described way. The Ransomware uses a complex file encryption algorithm to render certain file types inaccessible and to keep them hostage in exchange for money. During the encryption process, a special decryption key is generated which can reverse the complex locking algorithm and release the files. However, that key remains with the hackers who are conducting the attack. Once all the files have been sealed by the cryptovirus, the blackmailing scheme comes into play. If the victims follow the ransom demands of the criminals, they are promised to receive the decryption key. If no payment is released, the encrypted data is said to remain inaccessible for good.

The Qpss virus

The Qpss virus is a recently-released malware threat of the file-targeting malware category known as Ransomware. The Qpss virus will not damage your system or the files it encrypts but it will not release the locked data until you send its creators a certain amount of money.

The first thing that may come to your mind if you have been attacked is to pay the ransom. Of course, you can do so and hope that the hackers will send you the decryption key. Ideally, that key will reverse the encryption of your files and everything will get back to normal. However, in reality, things may not always go that way.

The hackers may sound very convincing and may try to use all sorts of tricks and threats in order to make you pay. After all, they really want your money. Once you send them what they want, though, can you really trust them? There is nothing on earth that could guarantee you that you will be sent the decryption key eve after you pay. In fact, if you’ve agreed to pay once, the cyber criminals may ask you for more money and may blackmail you again until you eventually realize that no matter how strictly you may follow their ransom demands, you won’t be able to please them and no key is going to be sent back to you. Because of this risk of losing your money without any guarantee about the future of your files, we strongly advise you not to opt for the money payment unless you’ve already exhausted all other available alternatives.

Indeed, there may not be many available solutions but it is still better to give a try to any alternatives which do not involve risking your money in vain. In the Removal Guide on this page, you will find some possible file-restoration steps, as well as instructions on how to remove Qpss from your computer. It won’t cost you anything to give them a try or do a bit more browsing on the Internet for other solutions. Even consulting a professional of your choice may be a better alternative than sponsoring the hackers and their criminal schemes. Another free tip we can give you in order to minimize your data loss is to check for file backups or copies which you may keep somewhere on external drives, on cloud storages or inside other devices.

The Qpss file decryption

The Qpss file decryption is a possible method of restoring files locked by the Ransomware but you will need a special key to complete it. If you don’t have the key needed for the Qpss file decryption, you will have to resort to some alternative options if you want to get your data back.

Sadly, there is no universal protection method which can keep your computer safe from Ransomware viruses as well as from other forms of malware. That said, if you are concerned about your system’s safety, there are a few basic safety rules to follow that can drastically decrease the chances of coming across another virus like Qpss, Hajd or Voom in the future.

First of all, keep in mind that the hackers may use many sneaky transmitters and delusive methods in order to mislead you and make you download the malware. That’s why, you should be cautious when surfing the web and use your common sense. Do not click on spam messages, different sketchy pop-ups, strange emails, with questionable attachments from unknown senders or too-good-to-be-true offers. In many cases, the contamination may happen with just one click on the wrong file or link. Also, keep your computer regularly scanned with reliable antivirus software and ensure that your OS is frequently updated. This way, the chance of new viruses such as Qpss (or other threats such as Trojans, Spyware, Worms, etc.) entering the system and remaining undetected would be minimal.

Remove Qpss Ransomware


Please bookmark this guide’s uninstallation instructions in your browser for easy access. In this way, you won’t have to look for the Qpss removal instructions after each system reboot that may be required. To make things even simpler, we recommend rebooting the system in Safe Mode, as this allows you to see what processes and programs (aside from the basic ones) are running and whether they are potentially harmful.

The Task Manager may be opened by pressing CTRL+SHIFT+ESC on your keyboard. Next, select the Processes tab and look for processes that use a lot of resources or have an unusual name. Right-click on a suspicious process and select Open File Location from the pop-up menu.


Use the free virus scanner below to check the files belonging to that process for malware.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    Delete any files the scanner has flagged as hazardous. It may be necessary to first stop a suspicious process from running in the Task Manager before removing its files by using the right-click options.


    When a computer is compromised, the Hosts file can also be altered. For this reason, you should check the “Localhost” section of the file for any malicious IP addresses. To access your Hosts file, just hold down the Windows key and the R key together and type the following command into the Run box:

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

    Once you do that, press Enter, and the Hosts file will open. Please let us know if you see any unusual IP addresses listed under Localhost by writing a comment below this guide. We will reply to you if we find the IP addresses you’ve posted to be dangerous.

    In the Windows search bar, type msconfig and press Enter. This will open the System Configuration window. Select the startup tab and look for Qpss startup elements. Remove their checkmarks and click OK to save your changes. Make sure, though, that you don’t remove the checkmark for entries that are legitimate and belong to the programs that normally start with your computer.

    A rising number of malware applications secretly install hazardous registry entries in order to evade detection and gain persistence. As a result, it’s a good idea to use the Registry Editor to search for and remove any Qpss-related files. Type Regedit in the Windows search bar and press Enter. The Registry Editor will now be shown on your computer’s screen. The CTRL and F key combination can be used to look for files that may have been inserted by the ransomware. The Find Next button may be used to search after you enter the name of the ransomware in the Find box.

    Delete any ransomware-related files that are detected by the search. After the initial set of results have been removed, the registry can be searched for files with the ransomware’s name as many times as necessary until no more results are found.

    Attention! Attempting to manually remove the ransomware from your registry may result in the deletion of other files. Therefore, using an anti-virus tool is the safest option, because it removes potentially harmful applications and dangerous registry entries without removing critical files.

    Traces of Qpss may also be found in the following five locations. So, once the registry has been cleaned, we recommend that you check them out by typing them in the Windows search bar and pressing Enter after each of them:

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Delete any questionable files you find in these locations. To remove all the temporary files from your Temp directory, you may press CTRL and A at the same time, then delete them by using the Del button on the keyboard.


    How to Decrypt Qpss files

    Non-professionals may have a tough time regaining access to data that was encrypted by ransomware. The methods required to decrypt the files may differ depending on the variant of ransomware that has been used to encrypt them. Ransomware variants are identified by the file extensions that are attached to the encrypted data.

    For the best results, before performing any data restoration, we recommend you utilize a professional virus removal application (like the one on this page) and carefully scan your computer with it. Once virus and ransomware scans have discovered no threats on the system, then it is safe to use alternative file recovery methods.

    New Djvu Ransomware

    Security researchers have discovered a new Djvu ransomware version called STOP Djvu. The .Qpss suffix on encrypted files indicates the presence of this danger on the computer. A decryptor like the one found at https://www.emsisoft.com/ransomware decryption-tools/stop-djvu may be able to help you recover data that was encrypted by this ransomware.

    Download STOPDjvu.exe from the URL above, and Select “Run as Administrator“. You’ll also want to check out the license agreement and any accompanying instructions of use before you start the actual decryption of files. Please be aware that this tool cannot decode data encrypted using unknown offline keys or online encryption.

    The anti-virus software on our page can quickly and successfully remove the Qpss ransomware if you run into problems throughout the eradication process. You can also use our free online virus scanner to check any questionable-looking files.
