Uyro is a ransomware-based program that is used in a blackmail scheme. The criminal creators of Uyro have set it to secretly encrypt digital files so that later they can blackmail the victims to pay a ransom for the decryption key.

Stop Virus 1024x550

If you store valuable data on your computer, Uyro represents a great danger to you because it can encrypt literally any type of digital information. Once the computer is infected, the virus starts to search it for files that are used most commonly by the user. These could be text documents, archives, databases, images, audio files, videos and other files. After being located, all these files get encrypted with advanced code that cannot be reversed without its matching decryption key.

Basically, the effect of the ransomware’s attack is that you are left with a bunch of totally unusable files that are present on the drive but cannot be opened. An additional suffix that is odd and unreadable by any program can be placed as the new file extension of the encrypted files. What is common for the Ransomware viruses is that they only work in stealth during the file encoding process. After that, they typically display a notification that serves to inform the victims about the attack and the steps that they need to take to decrypt their files. The hackers behind the infection normally request a ransom payment in exchange for providing the victims with a uniquely generated decryption key for their encrypted information.

Yet we have to warn you that things don’t always work this way. In fact, sending money to the criminals behind an infection like Uyro , Kcvp or Kcbu is very risky because you never know whether you will get a decryption key from them or not. The crooks may just disappear when they receive your money and you won’t be able to do anything about it. That’s why it is not the wisest course of action to fulfill the  ransom demands. Instead, our suggestion is to explore some of the options to remove the virus and save some of your data free of charge. For this reason we have come up with a removal guide that contains instructions on how to remove Uyro and suggestions on how to recover your information.

The Uyro virus

The Uyro virus is an online infection that does not corrupt or destroy digital data but only limits access to it for an indefinite period of time. What the Uyro virus does is it applies encryption to a number of commonly used files and then displays a ransom-demanding message on the desktop.

The fact that the ransomware does not cause harm to the files it encrypts and does not actually damage anything in the system helps it to remain invisible for the majority of traditional antivirus programs and allows it to complete its agenda in secret. That’s why, aside from investing in reliable security software, one of the best ways to prevent data loss due to file encryption is to create regular backup copies of your digital files on external drives, cloud storage or another device.

The Uyro file distribution

The Uyro file distribution is an arsenal of malware delivery techniques that the creators of the ransomware use to infect as many online users as possible. The Uyro file can easily be distributed via spam messages, malicious email attachments, torrents and cracked software.


No matter exactly how you’ve been infected, the ransomware should be removed from the device so that further file encryption can be avoided.

    If there are any dangers after the scan, you should stop the current process by right-clicking on it in the Processes tab and choosing End Process. The next step is to remove any files identified as threats in the File Location folder.



    If you suspect that there might be some unauthorized changes in your Hosts file, open a Run box by clicking Win + R and entering the following command, then hitting the Enter key.

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

    In the Hosts file, look for the word “Localhost” and double-check any IP addresses that don’t look reliable. If you find an IP that doesn’t appear legitimate, please let us know in the comments so that we may check into it and give you advice on how to proceed.

    The next stop on your journey should be the System Configuration window. To launch it, just enter “msconfig” in the search field of the Windows Start menu and hit Enter. When System Configuration appears, click on the “startup” tab to inspect the currently active startup items. 



    Uncheck the box next to any items you suspect may be associated with the ransomware. Then you may save your changes by selecting “OK.”

    The registry is another possible location where malicious software might conceal its components on a computer for as long as it needs to. That’s why, you should thoroughly scan the Registry Editor and remove any Uyro-related entries that you find there. Simply enter regedit in the Windows search field and hit Enter to open the Registry Editor.

    By pressing Ctrl + F, a Find window will appear, allowing you to search for infected file quickly. Type the name of the threat, such as “Uyro” in the Find box, and then click the Find Next button.

    Attention! It might be difficult for non-experts to remove ransomware-related registry entries. Moreover, there is a risk of system corruption if you wrongly delete registry files. For this reason, we recommend that you use the professional malware removal tool from our website if you are concerned that your computer is still infected and that Uyro-related files are hiding in an inaccessible location. This software may also be used to prevent future virus intrusions from sneaking in the computer.

    In addition to the registry, there are five other system locations on your computer that you should manually search for ransomware-related files. Simply type each of the search terms below in the Windows Search field and hit Enter to open them: 

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

    Inspect each directory’s files thoroughly, but remove entries only if you are certain they are part of the threat. To remove any temporary files, select everything from the Temp folder and hit the Del key on your computer.



    How to Decrypt Uyro files

    Ransomware threats are difficult to deal with, and the main reason for that is their encryption. Removing the malware that has encoded your data, oftentimes, does not make it accessible as it was before the attack. That’s why decrypting data encrypted by ransomware may be challenging even for specialists. Furthermore, ransomware decryption solutions may be very different for each ransomware variant. If you are determined to try everything possible to recover your files, our first recommendation is to check the encrypted files’ appended file extensions to identify the specific ransomware variant that you are faced with.

    Using a sophisticated anti-virus tool (like the one on our website) to do a comprehensive virus check is a must before any data recovery can begin. After making sure there isn’t a virus, you can start to look into file restoration options.

    New Djvu Ransomware

    STOP Djvu is a ransomware variant that has been wreaking havoc by locking users out of their data and asking a ransom payment from them. Victims in many parts of the globe have reported becoming the targets of this threat. Files encrypted by this new variant usually get a .Uyro extension. People that have lost access to their data, however, should not give in to the ransom demands since there are decryptors, like the one at the link below, that may be able to assist them regain encrypted data.

    Download the STOPDjvu executable file from the link above, and read the license agreement and the associated instructions before starting the decryption process. Keep in mind, however, that this tool may not be able to decode all types of encrypted data, particularly those that were encrypted using unknown offline keys or online encryption techniques.

    If the manual steps in this article are not adequate to address the problem, you may want to turn to a strong antivirus software to get rid of Uyro swiftly and efficiently. If you’re disturbed about the safety of a particular file, you may run a manual check of that file using our free online virus scanner.
