Efvc is a malicious piece of software that can encrypt your files and ask for a money transfer from you in return for decrypting them. The way Efvc operates proves that this is a Ransomware cryptovirus that is able to blackmail its victims for access to their most needed data.

The Efvc ransomware will leave a _readme.txt file with instructions

The following text addresses all the attributes of Efvc and ransomware representatives as a whole. Take your time and read it carefully in order to have a better chance to deal with this type of malware and to effectively remove it from your system. Most ransomware threats such as BbiiBbzz are used to firstly do something to your computer and then ask you to pay ransom in order to undo what they have done. Efvc, for instance, is a file-encrypting infection that blocks access to some of your data through encryption and demands a certain amount of money to provide you with a decryption key. The information below explains what the methods are that you can use to avoid paying the demanded amount, as well as what steps you can take to clean your computer from the infection.

The Efvc virus

The Efvc virus is a harmful program that renders users’ most important files inaccessible. After doing so, the Efvc virus tells to its victims that the only way to access their files again is to pay a certain amount of money to some anonymous hackers.

The Efvc virus will encrypt your files

Once this software infects your computer, its first task is to determine which files you are using the most and are of great value to you. These could be some documents that you’ve recently worked on, images, audio and video files, archives, databases and more. Encoding those files is the next step that ensures you cannot open or use them without paying a ransom. The hackers behind the infection typically tell you how to pay by displaying a message with instructions and deadlines on your screen. In exchange for your money, the crooks normally offer to send you a decryption key that can reverse the applied encryption.

The Efvc file recovery

The Efvc file recovery is an option that every ransomware victim has, as long as they agree to pay the demanded ransom. The hackers, who keep the Efvc file recovery key, however, may never send it to the victims.

Obviously, you have to make a choice on exactly how to deal with the ransomware. Unfortunately, regardless of what you choose to do, your encrypted files may never be usable again. Therefore, we sincerely believe that you should not risk your money by paying ransom to the hackers and seek some other alternatives that can help you deal with Efvc. For instance, you can check online for software that can help you remove the ransomware and recover some of your information. Or you can use our removal guide and the professional tool attached to it. Contacting a security expert is also an option that, despite costing you money, may still be able to help you more than sponsoring some anonymous cybercriminals. We cannot promise that your files will be returned with any of the alternative methods, but sending money to the hackers won’t do that either.

Remove Efvc Ransomware


Following the instructions in this removal guide is essential if you want to successfully remove the Efvc ransomware. In order to prevent the malicious software from communicating with its servers, turn off your computer’s Internet connection. Also, it is a good idea to unplug any external storage or USB devices that may have been connected to the infected system.

Once you do that, please click on this link and then follow the on-screen instructions to restart your computer in Safe Mode. After the reset, return to this page and complete the next step. If you bookmark this page now, you will be able to quickly access it after the reboot.

Once you’ve completed the first step and the computer has restarted in Safe Mode, open Task Manager by typing “task manager” in the Windows search field and pressing Enter. From there, choose the Processes tab. Sort the currently running processes according to their use of memory and CPU. The files connected with possibly harmful processes must be inspected. Each one may be accessed by right-clicking on the suspicious process and selecting Open File Location from the context menu.


Drag and drop the contents of the folder into the scanner below to run a check to determine if any possibly hazardous files need to be eliminated.

    If the scanner detects harmful files, the first step is to stop the related process from running by right-clicking on it and selecting “End Process“. After that, remove the files from their current location.


    Next, open the Run window by pressing Windows key + R at the same time, then typing the following command and pressing Enter:

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

    The Hosts file should be open on the screen. The comments section at the foot of this page is a good place to report any unusual IP addresses found under the “Localhost” section of the text. Those IP addresses you submit in the comments will be examined more attentively, and if they represent a risk to your computer, we will let you know.

    Some files related with Efvc may show up in the System Configuration tab. To open it, enter “msconfig” in the Windows search field and press the Enter key on your keyboard. Check the “startup” tab to see which startup items have been activated already.

    Remove any checkmarks from the boxes next to startup items if they are linked to the malicious software that has to be removed from your computer. Be sure to check the internet for more details before making any modifications if you have any doubts about a specific startup item before deciding to uncheck it.



    Malware may be able to hide in the registry for a long period of time by secretly installing new hazardous files. That’s why, a thorough registry search is required to identify any files connected with Efvc that need to be removed before the system can be restarted to prevent this danger from reappearing in the future. The Registry Editor may be launched by typing “Regedit” in the Windows search field and pressing the Enter key on your keyboard.

    It’s possible to use the CTRL and F keys on your computer to search the Registry Editor for infected files, which you can subsequently delete after the search has been finished. First, enter the ransomware’s name in the Find box and then click the Find Next button to begin your search.

    Attention! Ransomware-related files may be difficult to locate and remove from the registry if the user has never dealt with ransomware previously. System instability and harm might happen if legitimate registry entries are deleted. Thats why, a virus removal tool, like the one offered on our page, is strongly recommended if you don’t think that you can remove the infection on your own.

    Files linked to ransomware may also be found in the following places on a computer. To get to them, type the following search terms in the Windows search field and then press Enter:

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

    In the event that you find a file or folder with a name that catches your interest and looks like a threat, do some internet research to verify whether it genuinely has to be deleted from the system. You may also want to select all the files in your computer’s Temp folder and then hit the delete key to remove any temporary data that was saved there.


    How to Decrypt Efvc files

    Even the most experienced ransomware decryption experts may find it difficult to decode ransomware-encrypted data in certain cases. Many ransomware variants employ a variety of file-decryption techniques, making it difficult for users who are not familiar with these methods to deal with the threat effectively. That’s why identifying the ransomware version that has infected your computer is the first step in dealing with this kind of virus. The file extensions of the encrypted files may give you this information.

    If the ransomware is still present on your computer, any data that may be recovered will be encrypted. In order to avoid this, thoroughly inspecting the computer before commencing any data recovery procedure is a must. Anti-malware software may be quite helpful in these kinds of scenarios.

    New Djvu Ransomware

    STOP Djvu is a ransomware variant that is targeting a variety of data and it attacking a lot of computers all around the world. If your system has been infected by this variant of ransomware, the extension .Efvc is likely to be attached to the encrypted files. The good news is that decryption software like the one at the following link may be able to help those who have confirmed that their computer system is free of dangerous malware.


    Nevertheless, it is essential to thoroughly review the conditions of the license agreement and any extra instructions that may be attached to the decryptor before commencing the operation. Keep in mind, if your files were encrypted using an unknown offline key or an online encryption, you may not be able to decrypt them using this tool.

    If the manual methods indicated here fail to completely remove Efvc, you may need to use anti-virus software to do so. Using our free online virus scanner, you may do a manual scan on a file if you have any concerns about. A member of our team will do their best to respond to any questions or issues you may have regarding these removal instructions in the comment section below this guide.
