And we, at “How to remove guide” might just be able to help you. You will also find a step-by-step manual removal guide, a professional removal tool for automatic assistance, and some file-recovery suggestions.

Dealing with a malware of this type can be very challenging, and depending on the individual case, the recovery from the attack may not be fully possible. And while it is important to be aware of the fact you may not manage to restore all your files, we still encourage you to try the available alternative solutions that we will offer you below. Besides, removing the virus is a very essential thing that needs to be done if you want to be able to use your computer normally, so let’s dive in.

The Cceo virus

Cceo is a representative of the Ransomware category and, more precisely, the cryptovirus subcategory. As such, Cceo uses something called file encryption in order to cause harm.

It infiltrates the computer silently, after which it scans it for a specific list of file types. The most targeted ones typically are the most commonly used files, such as images, work documents, videos, audios, databases, some system files, etc. Once the Ransomware detects them, it immediately starts to create encrypted copies which can only be accessed with the help of a special decryption key. Lastly, the originals are removed from the computer and the victims are left with the inaccessible encrypted copies that no program can recognize or use. As soon as the encryption process completes, a ransom-demanding message gets displayed on the screen, asking for a ransom payment in exchange for the decryption key. The cyber criminals behind Cceo and Ccza typically ask for a certain amount of money to be paid to their cryptocurrency wallet, and threaten that if the payment isn’t made within the given deadline, you will never be able to access your files again.

The Cceo file encryption

Sending money to hackers is never a good idea. The people who create and spread the Cceo file Ransomware infections are only interested in extorting money from the unsuspecting web users. They couldn’t care less if their victims would eventually recover their data.

Unfortunately, this is still not enough to stop the victims from paying the ransom with the only hope that the hackers would maybe give them the decryption key. And while in some cases, this does happen, there are many cases where the victims never receive anything from the crooks. The latter simply disappear, leaving their victims in need of seeking other alternatives for dealing with the infection. This is the reason why we usually advise our readers to first explore the options, give a try to some other methods that can help them to remove the malware, and only if nothing works, to consider the ransom payment. A great starting point could be the removal guide below, with its manual instructions and the attached professional removal tool.

Remove Cceo Ransomware


To remove Cceo, one of the first things you’ll want to do is to disconnect your computer from the internet in order to prevent Ransomware from receiving commands from its remote servers. Next, unplug all of the USB and external storage devices that have been connected to the infected machine.

In order to remove Cceo more quickly, you should restart your computer in Safe. If you need help with that, click on this page and simply follow the steps there to restart the system in Safe Mode. Next, return to this page (you can bookmark it to keep it handy) when the system has restarted and move to the second step from this guide.

Pressing Ctrl+Shift+ESC at the same time will open the Task Manager on the infected machine. When you’re in the Task Manager’s tabbed toolbar, choose the Processes tab. The next step is to check for processes with unusual names in the list.

Search the internet for extra information on any suspicious-looking processes. Next, right-click on the process in question and choose Open File Location.


Scan the files located there using the scanner that you can find below to see whether they contain any malware.

    Stopping the running processes from the Processes tab is critical at this stage if you discover any threat in the scanned files. To stop the process, right-click on it and choose End Process from the right-click menu. Any files that the scanner flags as potentially dangerous should be deleted from their file location after that.


    To check for unauthorized changes in your Hosts file, use Win + R to open up a Run box, type the following command, and then press Enter.

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

    Look for any IP addresses under Localhost that don’t look reliable in the Hosts file. Leave us a comment if you see any IPs that appear questionable, so we can take a look at them and let you know what to do in case we find something unusual about them.

    The next system location that you need to check is the System Configuration window. Open it by typing msconfig in the Windows Search bar in the Start menu and pressing Enter. Next, go to the “startup” tab to see the startup items. Any startup item that you think is linked to the ransomware should have the checkmark removed from it. Click “OK” to save your changes.

    To get rid of any remnants of Cceo, the Registry Editor must be thoroughly scanned. The Registry may be accessed by typing regedit in the Windows search bar and pressing Enter.

    Next, click CTRL and F at the same time in the Registry to open a Find box, which will allow you to search for files related with the ransomware. Type in the threat’s name and then click the Find Next button to begin searching.

    Attention! Removing ransomware-related files from the registry might be challenging for those who aren’t tech-savvy. What is more, deletions and changes in the registry might lead to major system problems if done incorrectly. For this reason, we recommend using the professional malware removal program mentioned on our website if you believe your computer is still infected and that Cceo-related files are hiding somewhere on your system. Using this software, you may even prevent your computer from being infected with new viruses and threats.

    Aside from the Registry, Ransomware files may be located in the locations listed below. Once you’ve typed in each of the following search phrases in the Windows Search bar, press Enter to open the results.

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

    Search for dangerous files but don’t remove anything unless you’re very sure it’s a danger. Selecting the Temp folder and using the Del key on the keyboard will safely remove the temporary files from the system.


    How to Decrypt Cceo files

    Decrypting ransomware-encrypted data may be a difficult task because the decryption methods that can be applied may differ depending on the ransomware version that has attacked you. Your encrypted files’ file extensions might tell you what variant of ransomware you are faced with, so check that out first.

    A virus scan using a sophisticated anti-virus tool (such as the one on our website) is essential before any data recovery can begin. Only when the system has been scanned and found to be clean can you look into file recovery alternatives and give them a try.

    New Djvu Ransomware

    STOP Djvu is a new Djvu ransomware threat that locks up data using strong encryption, and then demands a ransom payment from the victims in order to decrypt it. Many victims have come forward to reveal that the files encrypted by this threat typically have the .Cceo suffix attached to them. A good thing to remember is that even if you’ve lost your data due to the Cceo encryption, you may try using decryptors like the one at the following site and try to recover it.

    You can download the STOPDjvu executable file from the link above, but before using it, make sure that you carefully read the license and the related instructions for use. Keep in mind that this program may not be able to decrypt all kinds of encrypted data, especially files that have been encrypted using unknown offline keys or online encryption. Still, we encourage you to give it a try and avoid paying the ransom at all cost.

    Cceo can be removed quickly and effectively using powerful anti-virus software if the manual steps in this guide fail to do so. By using our free online virus scanner., you can also do a manual scan on any file you’re worried about and scan it for malware.
