Bozq is a ransomware-based piece of code designed to require ransom from its victims in exchange for restoring access to their previously encrypted files. Typically, Bozq firstly encodes the files that are of great value to the user with complex cryptography and then demands a money transfer to decrypt them.

Ransomware describes a range of fraudulent computer programs that deny targeted users access to their digital data. Bozq is one such malware piece that usually encrypts a variety of files, which then can take a lifetime to recover. The hackers who control this piece of malware typically demand a ransom payment in order to send the victims a secret decryption key. Nevertheless, even if you are ready to transfer the required money, you will have no assurance that the files that have been encrypted are going to be successfully decrypted and made available to you. Therefore, at the end of the following post, we have created a removal guide to help you remove Bozq and potentially get back some of the files it has encrypted through system backups.

The Bozq virus

The Bozq virus is a malicious infection from the ransomware type which is programmed to prevent users from accessing the information stored on their computer. The ultimate goal of the Bozq virus is to blackmail its victims to pay ransom in order to access their files again.

Bozq more frequently infects the computer via an infected file that gets clicked on by the unsuspecting web users. This could be a fake advert, an infected email attachment, an executable file that has been compromised or even a web link that carries the infection. Once inside, the malware creates a list of the most commonly used data by searching all of the hard drives and other connected storage devices. Then the nasty virus encrypts this data and displays a scary ransom message on the screen. Sadly, the infection normally becomes apparent only after essential files have been encoded and the threatening message has appeared on your computer.

The Bozq file encryption

The Bozq file encryption is a secret process aimed at encoding user files and rendering them inaccessible. The Bozq file encryption is carried out in the background of the system and can complete its agenda under the nose of most security programs.

If you are hesitant whether to pay the ransom that Bozq demands or not, you should take into account that, according to some laws, making such a payment can be regarded as criminal activity. In doing so, you basically would encourage the hackers behind the ransomware to pursue their illegal practices and attack more and more web users who are willing to pay. Therefore, it is much better to seek some legitimate solutions to deal with the infection and recover your files by other means. What we suggest is to remove the infection from the computer with the help of the steps shown in the guide below. This will allow you to later use the instructions in the file-recovery section or even connect your personal backup sources to the clean computer.

Bozq Virus Ransomware Removal


Completing the instructions in this removal guide from beginning to end is crucial if you’re trying to remove Bozq effectively. For your convenience, we suggest bookmarking this page, so you can have quick access to the steps, as well as restarting the computer in Safe Mode to make it simpler to identify ransomware-related files and processes that are running on the system.

Once the computer reboots, return to this removal page that you have bookmarked and complete the following instructions:

Type msconfig in the search bar of the Start menu. Press Enter and then choose the Startup tab in the System Configuration window:


Make a thorough examination of the computer’s startup items, looking for anything that doesn’t seem to be connected to any legitimate software or activity. By unchecking the corresponding checkboxes, you may deactivate any suspicious-looking entries that have an “Unknown” Manufacturer or entries that you don’t trust.

After you’ve verified that only legitimate programs are enabled there, click Ok and exit the System Configuration window

Next, you’ll need to go through your computer’s processes one by one and end any that are associated with Bozq.

CTRL + SHIFT + ESC may be used to open the Task Manager. Then choose Processes from the tabs at the top.

Find processes with random names or processes that use a lot of resources, right-click on each of them and choose Open File Location to view their files:


Next, use the free online virus scanner below to check whether the files you’re looking at are dangerous or not.

    These files may need to be deleted from the File Location directory promptly if they are flagged as malicious. But before that, select the process they belong to from the Processes tab, right-click on it and choose the End Process option to stop it from running.


    Changes to other system files are possible as a result of certain malware attacks. Thus, in the event that you’ve been infected with Bozq, you should do the following:

    Use the Windows and R key combination and copy + paste the line below in the Run command box that opens on the screen:

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

    Click the OK button and open the Hosts file.

    Next, locate Localhost by scrolling through the file’s content. Afterwards, look to see if any suspicious IP addresses have been added below:

    hosts_opt (1)

    If you discover anything worrisome (like the Virus Creator IPs in the sample image above), please copy any IP addresses that look suspicious to you from your file, and paste them in the comments’ section. A member of our team will check them and give you their recommendations. 

    If there is nothing unusual in the file, close it and proceed to the next step.

    One of the most critical steps in dealing with the ransomware infection is to thoroughly inspect your computer’s registry for any suspicious entries, which should be deleted if they are found. 

    Begin by selecting the Start menu (bottom left) and entering Regedit in the Windows search bar. After pressing Enter to activate the Registry Editor, press CTRL and F at the same time on the keyboard. You’ll see a Find box on the screen at this point. Once you’ve entered the ransomware’s name, click the Find Next button to begin searching for registry entries that are a match. 

    Be very cautious when deleting items that aren’t directly connected to Bozq; else, your system might suffer irreparable harm. If you aren’t certain about the files that you need to delete, please use a professional removal tool to clean the registry safely.

    After that, check each of the locations listed below to see whether anything new has been added to them. Simply type each of them in the Windows Search field and open the folders:

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

    The Ransomware may have infected the directories with files that are named in a strange way, and deleting them may be necessary. Also, you need to remove any temporary files produced by the ransomware when you access the Temp folder by selecting all of its content and deleting it.


    How to Decrypt Bozq files

    Ransomware victims’ primary worry after removing the infection from their computer is how to regain access to their encrypted data. But this is something that has to be addressed carefully.

    It is highly recommended that you use professional anti-virus software, such as the tool that you can find on this page, for removing Bozq and other malware. If you are certain that Bozq has been effectively deleted from your PC, you may want to refer to the following instructions:

    Decrypting encrypted data varies depending on the version of the ransomware that has attacked you. Look at the extensions of the encrypted files to figure out what’s the ransomware’s version.

    New Djvu Ransomware

    STOP Djvu is the latest Djvu ransomware strain. The victims can easily recognize the infection  because the files that it encrypts come  with the .Bozq extension added to them. Presently, to decrypt data encoded by STOP Djvu, your only chance  is if those files have been encrypted using an offline key. This decryptor may help you recover your files:

    The STOPDjvu.exe file may be downloaded by clicking the Download button on the provided link.

    After you have downloaded the file, select “Run as Administrator”, then press the Yes button to start the software. Click the Decrypt button to begin the decryption procedure once you’ve read the license agreement and the short instructions. This decryptor can’t decode data encrypted using unknown offline keys or online encryption, so bear that in mind.

    If you have any troubles with this manual removal guide, please leave us a comment, and we will do our best to reply you shortly. Also, don’t hesitate to use the anti-virus software on this page to remove Bozq completely or check any suspicious-looking files with the free online virus scanner
