The Vook File

Both regular internet users and businesses can become targets of a new ransomware threat known as the Vook file. When your computer or network gets infected with this ransomware, you might see some clear signs. Your files, like photos and documents, might get locked, and you won’t be able to open them. The hackers usually leave a message asking for money in exchange for a key to unlock your Vook files. Sometimes, they even take over your computer screen with their message. Your computer could start acting strange, slow down, or even become unusable. It’s a pretty scary situation, but it’s essential to stay calm and not pay the ransom because there are often ways to recover your data without giving in to the hackers’ demands.

How to decrypt Vook ransomware files?

Decrypting Vook ransomware files is a tricky business, and whether you can do it depends on a few things. Different types of ransomware use different codes to lock up your files, and some codes are harder to crack than others. Sometimes, people who fight cybercrime come up with tools to help unlock the files. But it’s not a sure thing. Paying the ransom might seem like a quick fix, but it’s risky because there’s no guarantee you’ll get your files back, and it encourages the bad guys to keep doing bad things. So, it’s much better to protect yourself from ransomware in the first place. Regularly back up your stuff, keep your computer programs updated, and be careful where you click online to avoid getting into this kind of mess.

How to remove Vook ransomware virus and restore the files?

Getting rid of Vook ransomware from your computer is doable, but getting your files back can be a real puzzle. First, to remove the ransomware, you can use special computer programs or get help from cyber experts. But here’s the tricky part: even after the bad software is gone, your files might still be locked, and paying the ransom might not help. So, if you ever get hit by this malware, it’s smart to talk to cyber experts for advice, but be ready for the chance that you won’t ever see those files again. The best plan? Protect your computer from ransomware upfront by keeping your stuff backed up, your software up to date, and being super careful online.

The Vook virus

The cybercriminals behind the Vook virus usually demand payment through cryptocurrency like Bitcoin. They do this because cryptocurrency is hard to trace, making it easier for them to stay hidden. They leave a message on your computer screen explaining that your files are locked, and they tell you how much money they want to unlock them. The crooks might also give you a deadline, saying you have to pay by a certain date, or they’ll delete your files forever. They provide instructions on how to buy the digital money and send it to them. It’s important not to pay the ransom, as there’s no guarantee they’ll actually unlock your files, and it only encourages these cybercriminals to use the Vook virus in more attacks.

To protect against Vook ransomware, it’s a good idea to back up your data regularly, like once a week or even more often if you can. This way, if your computer gets infected, you’ll still have copies of your important files stored safely. Make sure to store these backups on an external drive or in the cloud, separate from your main computer. This will ensure that even if Vook ransomware locks your files, you can easily restore them without having to pay any ransom. To make your backup strategy even more robust, use multiple backup locations. Plus, consider automating your backups, so you don’t forget. Remember, the key is to have multiple copies of your data in different places, so even if one backup fails, you have others to rely on.


There are different types of ransomware, and they don’t all work the same way. Some ransomware, like the .Vook file-encrypting ransomware, locks up your files using strong encryption, making them inaccessible until you pay a ransom. Others, like screen-locking ransomware, don’t encrypt your files but make your computer’s screen unusable until you pay. Ransomware like .Vook can also target mobile devices like phones and tablets. How they get into your device can vary too, often through emails with infected attachments, suspicious websites, or downloads. So, it’s crucial to be cautious when online and not click on anything that looks sketchy.

Vook Extension

If you’ve paid a ransom to save your files from the Vook extension, but you haven’t received the decryption key, it’s essential to stay patient and not pay more. Sometimes, cybercriminals can be unreliable, and paying them won’t guarantee a solution. Instead, contact law enforcement and report the incident. They may be able to investigate and track down the criminals. Also, keep a record of all your communications with the hackers, such as emails or messages, as this could be useful for any investigation. In the future, it’s best to avoid paying ransoms and focus on regular data backups and strong cybersecurity measures to protect yourself from falling victim to the Vook extension and other ransomware attacks.


Unfortunately, Vook, Kool, Nood or Wisz ransomware is not limited to computers and can affect mobile devices like smartphones and tablets as well. When it infects a mobile device, it can lock the device or encrypt its files, making it impossible for you to access your data. In some cases, the Vook attackers might demand a ransom to unlock your device or decrypt your files. To protect your mobile devices from this ransomware, it’s crucial to avoid downloading apps from untrusted sources, regularly update your device’s operating system and apps, and be cautious when clicking on suspicious links or downloading attachments in emails or messages. Additionally, consider using mobile security software to add an extra layer of protection.

What is Vook File?

An Vook file can be any file that has been encrypted by the ransomware that has compromised your system. Paying a ransom to the cybercriminals to save your encrypted file, however, can lead to legal consequences, as it may involve sending money to individuals or groups involved in illegal activities or sanctioned by authorities in some jurisdictions. The legal implications can vary depending on your location and the specific circumstances surrounding the ransom payment. Beyond potential legal issues, cybersecurity experts and law enforcement agencies generally advise against paying ransoms because there’s no guarantee of regaining access to your Vook file. Therefore it’s advisable to report ransomware attacks to the authorities and seek assistance from cybersecurity professionals rather than complying with ransom demands.

The next step is to look for any processes associated with the ransomware in the Processes tab of the Task Manager. You open the Task Manager, press CTRL + SHIFT + ESC keyboard keys together, then select the second tab from the top. Look at how much CPU or memory the processes consume, or look at their names to identify any suspicious-looking ones.

When you isolate a suspicious process and right-click on it, you can select Open File Location, and check its files for malicious code.


To be on the safe side, these files need to be scanned with an antivirus program. Those without access to a reputable anti-virus program can use the free online virus scanner provided below:

    If the scan results show that there is a danger, right-click on the process that is associated with the infected files and select End Process. The File Location folder must be cleared of all dangerous files before moving on.


    In the third step, we will explain to you how to look for any alterations to your system’s Hosts file that can indicate a possible hacking. To do that, hold down the Windows key and R at the same time, then copy/paste the line below in the Run window that pops on the screen and press Enter:

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

    In the text of the file, look for anything strange under Localhost, such as Virus Creator IPs like those on the example image below:

    hosts_opt (1)

    If you come across such IPs under “Localhost,” please leave us a comment below this post. They’ll be checked by a member of our team, who will tell you what to do if anything suspicious is found.

    As long as there are no unauthorized modifications in your Hosts file, you don’t need to do anything. Just close the Hosts file and return to the Windows Search field.

    Type msconfig in the search and press Enter:


    Select “Startup” from the tabs at the top, and be sure to do some online research on any startup items with “unknown” manufacturer or random names that you find in the list. If you find enough information that a specific startup item is dangerous and is connected to Vook, you can disable it by unchecking its respective box and clicking OK.

    Once it has gained access to the system, a ransomware like Vook has the potential to add malicious entries to the registry. What is more, it is possible that the malware could resurface if these registry entries aren’t removed. Therefore, you’ll need to go through your registry and carefully search it in order to completely remove Vook.

    Attention! There is a risk of system corruption when important registry files and apps are modified or deleted. For this reason, ransomware victims are advised to remove potentially hazardous files from critical system locations like the registry only with the help of specialized malware removal tools.

    If you want to proceed with the manual removal of Vook anyway, please open the Registry Editor and check for Vook-related entries that need to be removed.

    To do that, type regedit in the Windows search field and hit Enter. When the Registry Editor starts, press CTRL and F from the keyboard to access the Editor’s Find window. In it, type the ransomware’s name and start a search. If there are files with that name in the search results, they need to be carefully deleted. 

    Using the Windows Search field, run a new manual search for Vook-related files in each of the five locations listed below: 

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

     If there are no suspicious files or subfolders, you should not make any changes. However, if there are, you should get rid of them. To remove the ransomware’s temporary files, just delete everything in the Temp directory.


    How to Decrypt Vook files

    The decryption method for your encrypted data may be different depending on the type of ransomware that has attacked you. The file extension added to the encrypted files can help you identify which Ransomware variant has attacked you.
