Remove Cerber Ransomware and Decrypt Files

Cerber Ransomware is a dangerous ransom virus which was made to lock your computer and deny access to your own files. Just like other ransomware, this new threat will encrypt certain files on the computer. It also changes file extensions to .Cerber one and demand payment before you can regain access and reverse these changes. It demands user to pay an amount of 1.24 Bitcoins or roughly $500.

Normally, Cerber virus attacks a computer with the help of another malware, trojan, or virus. It find flaws on the system which it will utilized as an entry point so that the process is hidden to most antivirus programs. In fact, once Cerber Ransomware is inside the PC, it instantly disables any security function running on the target computer.

The lock window contains the following messages:

Your documents, photos, databases, and other important files have been encrypted! To decrypt your files, follow the instructions…

Cerber Ransomware looks for important files like documents, spreadsheet, images, music, and videos. Two new documents is then added which gives instructions to users on how to decrypt affected files. In addition, Cerber Ransomware blocks access to certain web sites especially security pages where you can download tools and utilities that are useful in cleaning the PC from threats.

Cerber Ransomware

System Restore of Windows may help in resolving issues with viruses and malware. However, it will not settle problems with encrypted files. If your computer is running on Windows Vista/7 or later, perhaps ‘Previous Versions’ may help restore files from backup.

Backup your files

One important step before proceeding with the procedures below is to backup your files. Ransomware attacks are not the same. Each has its own unique set of payloads, aside from encrypting the files with a complex method. Others tend to delete the infected files after a certain period, while others keep them concealed in hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, and there are instances where files suffer from damages during the decryption process.

So, it is better to create a backup copy of your entire Cerber-encrypted files right now.

Cerber Ransomware Removal Guide

The first thing to do is remove the Cerber virus before attempting the decryption. Remember that as long as the ransomware is active, it will repeatedly encrypt the files on the compromised computer.

Infection with the Cerber ransomware virus is dangerous to the system because it can inject files that run each time Windows starts. To prevent malicious files from loading, the Windows operating system must run with minimal processes, and this can be done through SafeMode With Networking.

Step 1 : Scan the PC with Combo Cleaner for Windows

Combo Cleaner is a trusted PC security and optimization tool equipped with a powerful virus and malware detection engine. This program can get rid of threat like Cerber through this procedure.

1. Download the application from the following page:

2. Save the file to your preferred location.

3. Double-click the downloaded file CCSetup.exe and install with the default settings.

4. At the end of the setup process, click Finish to run Combo Cleaner.

5. The tool will update the database file; please wait for this process to complete.

6. To begin checking for threats like Cerber, click on the Start Scan button. Wait for this scan to finish.

3. Install by double-clicking on the file.

4. If it prompts "Do you want to allow this app to make changes on your device?" please click Yes.

5. Next, it will display the Terms and Conditions page. Click the Install button to begin.

Screenshot of Terms by Sophos Home

6. Run the installation with the default settings. Please note that an internet connection is required in order to download important updates.

7. After finishing the installation, you must login to the dashboard. If you already have a Sophos account, please login. Otherwise, please enter your details and click on the Create Account button.

8. Once you are in the Sophos Home console, click the Scan button to start checking the computer for Cerber components.

Screenshot of Sophos Home

9. Scanning may take a while; please wait for this process to finish.

10. After scanning the computer, Sophos Home will start cleaning or deleting files infected with Cerber.

11. You may now close Sophos Home. The computer is now free from Cerber, as well as associated malware and viruses.

The above procedures should have totally eliminated Cerber ransomware. However, if you find that there are still remnants of the virus, please proceed to the next steps below.

Step 4 : Double Check with Windows Security Apps

Microsoft Windows has a built-in security application that you can use to double-check if your computer is still infected with Cerber. For Windows 10/11 users, please run Windows Security.

Windows 10 / 11 Instructions:

Windows Security is a free tool that was built to help you remove Cerber, viruses, and other malicious items from Windows 10/11 systems. Follow these procedures to scan your computer with the tool:

1. Tap or click the Search charm and search for Windows Security

2. Click Open to run the program.

How to protect the computer from Cerber ransomware?

After the ransomware is removed, it is important to prevent similar incidents from happening again. To effectively protect the computer, the user must know how Cerber ransomware was able to infect it. To minimize the possibility of infection, staying away from the common sources of this virus is crucial.

How does ransomware infect your computer?

The method of infecting the computers was found to be similar to that of other common viruses. Ransomware like Cerber is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and Trojan Downloaders.

Once the virus is executed, it immediately infects the system. Then, Cerber ransomware communicates with a remote server so that a unique key can be generated for a specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. In the final stage of the attack, Cerber ransomware demands ransom money in exchange for the decryption tool. To further understand the attack scheme, we have included an infographic below.

Infographic image of ransomware attack stages
You can print, download, or share the infographic by clicking the image.

What are the essential things to do?

Do a Regular File Back-up - Always backup your data on a separate storage devices such as external hard drives, optical discs, or online backup services.

Keep Your Software Updated - Make sure that you have the latest software updates especially on the operating system. Recent updates often contain vital security patches to help protect the computer against all forms of threats.

Install a Security Program - Protect the computer with effective anti-virus application using efficient real-time scanning. Regularly run a complete scan to check the computer for presence of malware.

Protect your files with Controlled Folder Access (Windows 10/11)

For Windows 10/11 users, aside from protecting the computer using anti-virus or anti-malware programs, one way to protect against ransomware attacks is by using Controlled Folder Access. This feature of Windows Defender Security Center may not prevent the Cerber ransomware infection, but it can protect folders and files in general. Follow the steps to enable Controlled Folder Access in Windows 10/11.

1. Go to Windows Search and type Windows Security.

Screenshot of Win 11 Search

2. Open Windows Security to see all the options.

3. Click Virus and Threat Protection, either on the sidebar or on the main panel.

Screenshot of Ransomware Protection

4. Scroll down to the "Ransomware Protection" area, and click on Manage Ransomware Protection.

5. In the "Controlled Folder Access" section, turn the slider to On. This will enable the feature and protect the folder against Cerber virus or any type of ransomware.

Screenshot of Controlled Folder

6. Click on Protected Folders to see the list of included folders. If Windows displays a message, "Do you want to allow this app to make changes to your device?" please click Yes to proceed.

Screenshot of Protected Folder

7. Click on the Add a Protected Folders button to include additional folders. Make sure that folders with important files are included in the list.

Troubleshooting Guide

Certain programs may be blocked by the Controlled Folder Access feature. To fix the issue, simply have the specific program whitelisted.

1. Under the "Controlled Folder Access" section, click Allow an app through Controlled folder access.

2. If Windows displays the message "Do you want to allow this app to make changes to your device?" click Yes to continue.

3. Next, click the Add an allowed app button.

Screenshot of Allowing App

4. Lastly, click on the Recently blocked app and remove the program from the list of blocked applications.

This Controlled Folder Access feature is one way to protect files against Cerber ransomware. Other important things to do to keep files safe against ransomware are early prevention, like keeping programs updated, installing an efficient security program, and doing regular file backups on a separate media drive.

    So far I hope I have removed the culprit, but still unable to decrypt the files.
    Every files had turned .cerber. Yes, I agree to many that we should not pay Cerber
    Yes, I also agree that we should do regular back up or that System setting what knot. Lesson learned.
    I hope that one day soon, some good souls will come out with a Cerber Decryptor tools.
    Keep calm & hope for the best.
    Thank you.

    PS- I lost a very important file. A video of my beautiful late grandmother. She passed away early this year. I hope someday the file can recover, decrypt with the help of you good people out there.

    My D drive and E drive has been completely washed out with this cerber virus. Can anyone please advice me on this on how to remove this virus. I don’t have restore versions to took my back up. I have lot of important files related to my work. Please help me on this, I am waiting.

  6. For last couple of weeks I’m searching for a solution to this Cerber ransomware. I had no idea of such malicious bug before. friends we all are victims. we lost invaluable things like memory of my dearest mother who passed way 3 moths back and lovely memory of childhood of my kids. Waiting with a hope soon Decrypter will come.
    friends if you find any thing please share to

  7. I got this problem. Don’t know how this cerber got into my computer. Hoping to solve this problem.

  8. I have the private key Cerber generated to encrypt my files. Is there a program which will use this key to decrypt my files?

  9. @os2wiz, I believe after getting the key, they will also provide the Decryptor program which will only work for your key.

  10. This virus is very dangerous I think. I have search many sites for this but, no use.

    Finally I got a solution for C:/ drive files. I got all the files back to normal format and for this, thanks to malwarefixes team. With the use of “Windows Previous Version Tool” at least I got some important files back.

    Simply right click on folder which you want to restore to normal format and click on “Restore previous versions” and select date. Click on “Copy” and give path where you want copy this folder.

    Bad thing is, except drive “C”, we were unable to get our files back to normal format from drives like D,E,F etc…

  11. SOLVED…

    With the use of “ShadowExplorer” software, we were able to recovered data from rom other drives as well. I got my files back to normal format. Feeling very happy that I got almost all files.

    Download and use “Shadow Explorer” software and you can easily get your files back.

    Thanks to Malwarefixes team for their effort. This site is very helpful. Giving good information to users without any cost (money).

    Once again thank to MALWAREFIXES TEAM!

  12. Dharmesh Panchal

    I lost my all type file like jpg, video, word ,excel, music. All files shows extensions like .cerber. Help decrypt my file

  13. I follow the instructions above but I can’t solve the problem because I have windows XP and with Shadow Explorer we cannot recover the files. Do you have any idea what can I do?

  14. I’ve tried to restore files with Panda Ransomware Decrypt in the advanced mode, but it the following error:
    Invalid or inaccessible folder selected, please select a valid folder or drive to search for encrypted files.
    What does this mean?

  15. Thanks. This was really helpful. I got off easy because only the PDF’s and a few unimportant images were infected before I noticed. Panda decoder is not helping and I don’t have previous versions but the rest is working. Thanks.

  16. Please let us known if somebody has a decryption tool.
    We had the problem on a XP PC, so there are no Shadow copies of the files.
    Thanks in advance.

  17. The Cerber decryption tool doesn’t work for me as described. I can’t select multiple files for decryption, and when I run a scan on an entire folder, it comes back with ONE infected file and no action taken. What am I doing wrong?

  18. Peter Maccabe

  25. I have been affected with this Cerber3 last week is there any way to recover my data I don’t even have a backup of it.

  26. Gautam Kumawat

    My PC has been affected with this virus on 13th September 2016 when I downloaded and installed desktop sharing software Ammyy. Hope someday there will be developed a Decrypter tool for Cerber 3.0. By that time I have resigned my valuable data to fate.

  27. Ivan Stoichkov

    Tengo el mismo problema que todos solo que a mi me pego en 3 servidores y una de ellos es contable, por el momento no hay una solucion definitiva para recuperar los archivos, seguramente aparecera en los proximos meses como se vaya infectando mas gente y esto resulte en un pandemonium, sin embargo es importante los respaldos constantes en medios extraibles y mantener actualizados nuestros sistemas operativos, antivirus y alti malware.

    Lo que estoy haciendo es colocar un disco duro nuevo y reinstalar sistemas operativo y aplicaciones, escanear los discos duros externamente, copiar los archivos infectados en otro disco duro, reintaslar el sistema operativo y apps para reiniciar la captura y recopilacion de archivos con cada usuario y esperar a que salga algun desencriptador.

    Tambien hay que enviar las evidencias a las compañias de antivirus y malware para ayudarles a encontar una cura.

    Trenmicro tiene un desencritador pero no funciona ara la version de cerber3, estare corriendo aplicaciones para recuperar archivos eliminados esperando recuperar algo mas de informacion.

    les mantendre informados en medida que avance mi caso.

    Bendiciones a todos y que pronto encontremos una cura para este mal.

  39. Ahmed_kurdistan

    Hey friends , solving this problem is hard , but you can just change extension . for ex : if you know your file is “mp4” so just change “cerber3” to “mp4” ,
    it worked like this for me , i hope it works for you too , :)

  40. Dear Sir,
    In my laptop files like doc, xls, jpeg etc. are attacked Cerber.3. Please help me convert to original format.

  41. Hamid Omarkhail

    Hello to all friends,
    I have lost some of my files and some are decrypted. How can i find and download the CERBER RONSOMWARE software, I need help. Please guide me.

  42. Recently, my files encrypted by Cerber ransomware with extension “.b1a5”. This is latest development in CERBER. Please let me know if there is any decryption software for this.

  43. My files was encrypted with .b823 extension. Renaming the extension doesn’t work. Please help me how to bet back my files. Thanks in advance.

  44. Hello I am also victim of Cerber3 ransomware. If anyone got its solution please reply here.

  45. I recently got infected by this ransomware Cerber! All my files have been encrypted. the file ext. is .affa. (cerber ransomware 4.0.1)
    can anyone please find a solution for this one.

  46. Recently got infected by this ransomware Cerber! All my files have been encrypted. the file ext. is .affa. (Cerber ransomware 4.0.1)
    Can anyone please find a solution for this one?

  47. My PC just got affected by this virus thing. I real need help ASAP. Guys, can anyone help me, I cannot even open my document because of this thing. Any one who have a setup of Crber Decryptor, please send me web site where I can download it myself.

  48. I tried TrendMicro and Sophos but none is actually working. Please I need help on this. Which other software can I make use of?

  49. If someone find a software to solve this out would pay very happy 30 euro to buy it. No second thought. The man who find the solution will be withy a lot of money very quick. I am victim too, extension is .a944

  50. If everyone would actually read the solution provided it will most likely help recover your files. The main issue here is going to be the network shares. Better hope you had a backup of them. The other main issue is the system restore too many leave this as default and there are likely few restore points and sometimes they are a ways back. You ARE going to lose everything between that point and now.

    If people would just have a decent backup off site and stop clicking on email attachments these issues would quit cropping up!

    Use the tools recommended above. Also, if you can do a system Restore to a date before the infection, that will remove the software that did this. Then use the tools like the shadow explorer to recover files and folders! Do run the anti-virus and malware tools to make sure things are gone! Remember to clear all temp folders and caches with CCleaner or similar tool. If more people above in the comments would actually spend 2 minutes and read the directions instead of saying help and running around like a chicken with their heads cut off there would be less issues and more fixes.

    Face it ransomware is here to stay. Avoid the risky behavior and opening and blindly following prompts and you will avoid 99+% of the malware and viruses out there.

    Thanks to the Malwarefixes people for the very well done instructions and tool links.

  51. Dear Sir,
    In my laptop files like doc, xls, jpeg etc… are attacked by Cerber3. Please help me convert to original format.

  52. @Col Temp

    I wish to thank you for your advice. I did a system restore three times from 3 different dates. The last one took. I had only just last Sunday restored temporarily back to XP as W7 on my hard drive had failed and I managed to do my college work and recover some documents – then this Ransomware began to plague me. ESET was catching and cleaning all of them but it was still going on and multiplying into the 100’s. So l saw your note above and decided to restore. And thank you so much all appears well. And no pop-ups from ESET. I will take note of your advice and I will be very careful and back up.

  53. Please help, my whole file in my computer was encrypted with .84e0 extension with HELP_HELP_HELP files. I have tried with all malware remover and Decryptor apps but it can not bring my data back. what should I do?

  54. Hi I am new victim of .Adobe Ransomware in FEB 2019 failed to recover my all files and I have no 650 $ please support if any one have some solution for it.
