Wisz File

It’s possible you’ve ended up on this page because you’ve come across an Wisz file on your computer that just won’t respond, no matter what you do to open it. If you’re confused by this, the reason is linked to a special secret code that’s been added to this file, making it really tough to access. The situation can only be solved with a special decryption key, without which, the file remains stubbornly locked up. Generally, users who spot an Wisz file on their computer think of one thing – a potential encounter with something called ransomware. This kind of online trouble involves tricky hackers locking up your important files with encryption and asking for a sort of virtual payment to set them free.

How to decrypt Wisz ransomware files?

Unlocking your encrypted files affected by Wisz, Lkhy or Lkfr ransomware requires delving into the web space for decryption tools. You need to do a comprehensive search to find potential solutions tailored to the specific variant of ransomware that has targeted your data. Trustworthy cybersecurity organizations and online forums are a great place to look for this kind of information as they often offer valuable insights and resources that could prove essential in your quest for file restoration. While the idea of paying the ransom might cross your mind, it may not yield the desired outcome, as cybercriminals might not uphold their end of the bargain, and supporting their illicit endeavors is far from recommended.

How to remove Wisz ransomware virus and restore the files?

Removing the Wisz ransomware virus and restoring your files requires disconnecting your infected device from the Internet and any connected networks. Aside from that, you need to find the exact variant of ransomware that has infiltrated your system, as this knowledge will serve as your compass for removal. Use a trustworthy antivirus software to conduct an exhaustive scan of your system, and effectively eradicate the ransomware. If possible, manually eliminate any suspicious files linked to the threat. Once the virus is removed, you can explore file recovery options such as backups from external sources or reliable cloud services.

Wisz Virus

The Wisz virus is an extremely hazardous type of ransomware that often sneaks into computers by taking advantage of malicious email attachments found in spam messages. When these attachments are opened, the ransomware activates and quickly starts encrypting important files on the computer. The harmful program also spreads through downloads from compromised websites, tricky ads, pop-ups and malicious links. It also can hide inside files that seem harmless, like zipped folders, hidden parts of Microsoft Office documents, or web offers that look safe. Therefore, if you want to stay away from the Wisz virus, it’s crucial to avoid clicking on suspicious links, unknown attachments, random files and ads that look too-good-to-be-true.

To protect your computer from Wisz, it’s essential to grasp the risks linked to dealing with questionable online content. Boosting your defense involves getting strong security software that can keep an eye on your system all the time. Just as important is keeping your software updated, which helps lower the chances of hackers exploiting weak points that people often don’t fix. But the most potent defense against Wisz is creating backups of your data on a regular basis. Copying your important files onto an external device or a secure online storage spot can prevent you from losing your data forever in case of a ransomware attack.


The Wisz ransomware uses a complex file encryption which ends with .Wisz to silently lock up your digital files, making them impossible to open. Dealing with this kind of encryption can be tricky because it requires a special decryption key which is offered by the ransomware operators for a ransom. If your files have fallen victim to the .Wisz encryption, it’s important to resist the urge to pay the ransom demanded by the hackers. That’s because giving them money doesn’t guarantee you’ll get the key to unlock your files. For this reason, we recommend trying out different methods to recover your encrypted data, like the ones explained in the guide below.

Wisz Extension

The Wisz extension is like an extra tag or part of a file’s name that the Wisz ransomware sticks onto encrypted files to show that they’ve been locked up. This extension helps tell apart the files that got encrypted from the ones that are still normal. For example, if you had a file named “table.exe” and the ransomware got to it, it might change the name to “table.exe.Wisz” to show it’s locked up. But here’s the catch: just removing the Wisz extension or changing the name back doesn’t magically unlock the file. To really unlock it, you usually need a special key from the ransomware crooks or certain tools made for decryption.

Wisz Ransomware

The Wisz ransomware is like a sneaky digital bandit that takes your files hostage by locking them up with a secret code, making them impossible to use. It even gives your files a special name tag, sort of like putting them in a virtual jail. Then, it shows you a message asking for money in a cryptocurrency to free your files. This tricky Wisz ransomware is really good at what it does – it uses strong encryption that is super hard to break without a special key. Sometimes it even messes with your computer’s normal functions and the way it connects to the Internet. This can cause a lot of trouble, like losing your important data and even putting your private info at risk. So, to stay safe from this digital troublemaker, it’s crucial to have good computer defenses and to keep extra copies of your important files in a safe place.

 What is Wisz File?

The Wisz file is as a computer file, stored on your system, that has been locked up by a ransomware. Essentially, a secret code that nobody can read has been applied to that file, turning it into a jumbled mess. To make things worse, the ransomware can do this to all sorts of files, like your important documents, pictures, videos, and more. The targeted files typically get a special name tag once they get encrypted, and the cybercriminals who control the malware ask for money to decrypt them. It’s a bit like a digital kidnapping followed by a brutal blackmail! So, if you ever see an Wisz file on your computer, it’s a sign that you might be in trouble, and it’s important to be cautious and get help.

Ransomware infections such as Wisz often operate their malicious processes in the background of a computer’s OS, showing no obvious symptoms that could potentially expose them. This permits them to remain undetected while wreaking havoc on the system. In order to deal with this form of virus, one of the most difficult tasks is to identify and stop any potentially harmful processes related with the ransomware that may be operating on your computer at the time of infection. To do that, it is necessary to carefully follow the instructions outlined below.

Open the Windows Task Manager by pressing the CTRL+SHIFT+ESC keys simultaneously, and then pick the Processes Tab from the list of top-level tabs in the Task Manager window.

You should make a note of any processes that consume a significant amount of resources, have an odd name, or otherwise look suspicious, then right-click on each of them to bring up the quick menu. To check the files connected with that process, select “Open File Location” from the quick menu.


Check the files associated with the process in question for potentially dangerous code by running them via the free online virus scanner given below:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    As soon as a file is discovered to be hazardous, the process that is associated with it should be stopped immediately, and the files themselves should be carefully removed from your computer.

    The same should be done for each process that includes potentially harmful files until the system has been totally cleared of all rogue processes.


    In the next step, it is necessary to deactivate any potentially harmful startup items that have been introduced to the system by the ransomware.

    For this, begin by entering msconfig in the Windows search bar and then choosing System Configuration from the list of search results that appears. Then read through the items under the Startup tab, looking for anything out of the ordinary:


    When a starting item has a “Unknown” Manufacturer or a random name, it is suggested that you study it online and uncheck its checkbox if you uncover sufficient proof that it is associated with the ransomware. In addition, check for any additional startup items on your computer that you are unable to associate with the applications that you usually launch on startup. You want to keep only startup items associated with applications that you trust or that are connected to the system.

    Another very important step if you want to eliminate all traces of Wisz from your system and prevent the ransomware from re-appearing or leaving malicious components behind is to search the system’s registry for any potentially hazardous entries that have been secretly added there.

    The Registry Editor may be accessed by typing Regedit in the Windows search bar and pressing Enter to bring up the Registry Editor. After that, you may search for the ransomware more rapidly by pressing the CTRL and F keys on your computer at the same time and carefully typing the name of the malware into the Find box. Next, click the Find Next button, and if any results are returned, carefully remove the entries that include the name of the malware.

    Attention! You should never remove entries from your registry if you aren’t absolutely positive you want to remove them, since any incorrect deletions might cause more harm than good to your system. Therefore, it is recommended that you use professional removal solutions to completely remove Wisz and other ransomware-related files from your computer’s registry in order to prevent any harm.

    Once you are done with the registry, close the Registry Editor and manually search for each of the locations listed below by using the Windows Search bar. Simply copy/paste the following lines and then press Enter after each to open them:

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

    Search for suspicious files and folders that are associated with the threat, and remove anything that you strongly believe to be hazardous. If you want to get rid of any temporary files that may have been saved on your system, select and delete everything in the Temp folder.

    The next location that you need to check is your computer’s Hosts file. Once you get there, you need to search for any alterations that may have been made without your knowledge.  If you come across anything unusual, please leave a comment below and we will try our best to respond to you as soon as possible.

    In order to access the Hosts file, press the Windows and R keys together. This will immediately open a Run box, where you need to copy/paste the following command and hit the Enter key to have it executed: 

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

    As seen in the accompanying screenshot below, please notify us if your Hosts file has been updated to contain certain suspicious-looking IP addresses under the Localhost section:

    hosts_opt (1)

    If everything appears to be in order to you, simply close the file without making any modifications.


    How to Decrypt Wisz files

    Depending on the ransomware variant that has infected your computer, you may need to take a different strategy in order to successfully decode the encrypted data. The first thing that you need to do is to look at the file extensions that the virus has added to the files that have been encrypted in order to figure out which Ransomware variant you are dealing with.

    New Djvu Ransomware

    STOP Djvu Ransomware is the latest variant of the Djvu Ransomware family to infect computers. To check if you have been infected by this new danger, look for the .Wisz file extension at the end of the files encrypted by the virus. Typically, this extension is automatically added to the files encrypted by the malware. The good news is that there is a way to decrypt the files if they have been encrypted with an offline key. In fact, if you click on the following link, you will be sent to a page with a decryption program that you might find useful in your case.



    You can run the decryption application by downloading it from the URL above, right-clicking it, selecting “Run as Administrator”, and then hitting “Yes”. Please take a moment to review the licensing agreement as well as the brief instructions that display on the screen before moving further.

    Decryption will be activated by selecting Decrypt button, which will start the process of decrypting the data that has been encrypted. Note that data encrypted using unknown offline keys or online encryption may not be decrypted by this program. If you have any questions or issues, please share them with us in the comments section below, and we will do all we can to help you out.

    Important! Remember to check your computer to make sure that any ransomware-related files and harmful registry entries have been deleted from it before attempting to decrypt the data that has been encoded. Online virus scanners and anti-virus software, such as those available on our website, will aid you in eliminating Wisz and other harmful pieces of malware that are spreading over the internet.
