Zfdv virus Removal Guide

Description of Zfdv ransomware

Zfdv ransomware is an infection that spreads quickly on the system and locks user files

Zfdv ransomwareSuch a virus demands to pay a ransom, promising to decrypt locked files

The Zfdv file virus is a type of ransomware infection that uses sophisticated encryption to cause direct damage to the files on your computer, prompting victims to pay the required ransom. This claim is made using the _readme.txt ransom note. This is the message from cybercriminals who created the virus to easily profit from users who no longer have access to their personal files that are critical to them.

Criminals encrypt commonly used files and data that can be valuable to the victim. Zfdv ransomware virus encrypts documents, images, audio files, etc. In addition, this infection can alter or corrupt some system data to ensure its successful operation, resulting in reduced computer performance, various errors, and other crashes.

Zfdv virus can harm your computer system by performing additional malicious processes and installing other infections that control the performance of your computer. Trojans and other malware entering the system can further damage an already problematic device. So it is important to understand that locking personal files alone is not the only problem caused by a ransomware virus.

The Zfdv file virus is not a new threat as it comes from a family of infections known since 2018. This is the latest version of specific ransomware that cannot be decrypted. The developers of Ransomware change some of the threat features and code, but the ransom note and the message in the text file remain the same. While this is one of the most devastating infection types out there, you should not immediately panic and definitely not instantly hand your money to cybercriminals. In this article, we will explain the correct way of handling the situation – delete the virus, attempt to restore files in alternative ways, and repair damaged system components.

Name Zfdv ransomware
Type Cryptovirus, file-locker virus
Family Djvu ransomware
Marker .zfdv
Distribution This infection is spread through pirated software or game packages, spam emails attachments
Contact information admin@helpdata.top, supportsys@airmail.cc
Ransom amount Cybercriminals demand to pay $ 490. After 72 hours, that amount doubles to $ 980
Ransom note _readme.txt
Elimination This threat can be eliminated with a reliable antivirus program
Repair With a program like ReimageIntego, you can automatically fix corrupted system files

Cybercriminals are trying to persuade people to pay the required ransom by promising to send a decryption tool for the money. They even offer to decrypt any trial file for free, as this will gain the trust of the victims. However, even if you pay the full required $ 980 in bitcoins, there is still no guarantee that the people who created this virus will actually send the decryption tool and it will really work. Unfortunately, cybercriminals often disappear as soon as they receive money, and .zfdv files remain locked. Or worse, they demand even more money after receiving the first payment.

Cyber security professionals are constantly alerting people about this threat. Once your files are encrypted, they can no longer be opened or used. The only way to recover encrypted data is to use a specific key or password held by cybercriminals. However, there is no guarantee that even after paying the ransom, the developers of the Zfdv ransomware virus will send the necessary tools, so it is not worth the risk and it is better not to contact them at all.

Zfdv file virusDue to encrypted files, some victims are willing to pay the required ransom, although this is not recommended

Ransomware is a serious virus that can quickly spread through your computer system and seriously affect your device. Unfortunately, this is because users often behave irresponsibly. For example, users download suspicious email attachments or click on a suspicious link, install pirated versions of programs, etc.

How to remove this threat

Zfdv ransomware virus damages the device, so the infection removal process is very important and necessary. You cannot restore files on a system that is still running this virus. This is risky and quite dangerous, as a ransomware program can encrypt newly added files even after the initial encryption.

To remove such a threat, you will need a security program that can detect Zfdv ransomware and other related or accidental threats. We suggest trying SpyHunter 5Combo Cleaner or Malwarebytes. When you run the AV program, you can scan your system and find any infected files. After successfully completing the scan and getting rid of the virus, you can re-scan the system to make sure that there are no residues left.

Sometimes these threats are spread through trojans and other infections, so deleting the virus with an antivirus program helps to remove not only the Zfdv file virus but also other threats. Do not pay the required ransom and do not even think about contacting the cyber criminals who caused this infection.

System repair and file recovery options

Zfdv ransomware can do a lot of damage and affect system files, functions and computer performance. These changes are made in order for the virus to successfully survive on the system and encrypt the files. The ransomware also works on certain features of the device, making it much harder to permanently remove this problem from your computer.

There are various files and programs that are affected by Zfdv ransomware, making it difficult for users to recover damaged files. These issues can severely affect the performance and security of your computer. This is why it is very important to get rid of the virus completely and make sure that all its remains are deleted.

When ransomware and other viruses infect the machine, various processes get affected. Windows registry entries, other directories, and databases of system files can get damaged or corrupted. Affected files can lead to additional system issues. Malware damage to such files triggers problems with performance and stability, and security issues. Windows operating system recovery is needed then.

You should rely on proper tools that are designed to repair such files, and recover smooth performance. ReimageIntego is developed with the purpose to fix damaged files, repairing processes, and removing other pieces of malware that get leftover. The program has a few engines and databases where needed Windows files can be found and repaired. This application also wan fix errors related to registry, damaged DLLs, and other system files.

You can avoid manual file repair that when done incorrectly can trigger more serious damage. Automatic system repair means that you do not need to reinstall the OS or different files.

As we mentioned before, this ransomware is not new. The infection may have different contact emails and use different file markers, but in all other respects, the Zfdv virus is identical to older versions. Unfortunately, this means that the decryption options are limited due to the encryption keys used during the encryption process. However, you can still check one method that helps unlock files in some cases.

There is an option for some of the versions in this Djvu family – a decryption tool that works with offline ids. You should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone due to malware methods of encrypting files differently.

Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.

  • Download the app from the official Emsisoft website.
  • After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
  • If User Account Control (UAC) message shows up, press Yes.
  • Agree to License Terms by pressing Yes.
  • After Disclaimer shows up, press OK.
  • The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
  • Press Decrypt.

From here, there are three available outcomes:

  1. Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
  2. Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
  3. This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

Don’t pay cybercriminals and try to remove the virus as soon as possible. SpyHunter 5Combo Cleaner and Malwarebytes can help you get rid of the infection easily and quickly. Only after removing the virus, you can try to recover files that have been encrypted by this threat. System repair tools such as ReimageIntego also help ensure that the remnants of the Zfdv file virus no longer damage the device, so that these affected files can be safely restored using backups.

Getting rid of Zfdv virus. Follow these steps

Software for file restoring

Data backups are important, but users tend to skip such an important step. Also, ransomware comes without notice, so many files affected by the threat can be the ones that haven't been backed up yet. paying the demanded ransom is not the solution, so trusting criminals is not the option for file recovery.

File recovery is a difficult thing, but it is possible to retrieve those files that get affected or encrypted, in some cases. It is highly related to the fact that there are many methods to lock files. The encryption algorithm used can determine if decryption is possible. Since there are thousands of ransomware strains, it is impossible to tell if any software will work for you.

We suggest trying the program regardless of which ransomware attacked your computer. Make sure to pay attention to some details before you begin:

  • Note that encrypted data on your computer might get permanently damaged by security or data recovery software, you should first make backups of it to save crucial data.
  • Make sure to recover your files using this method after you perform a thorough system scan with anti-malware software.

How to prevent from getting ransomware

A proper web browser and VPN tool can guarantee better safety

As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service. This tool successfully reroutes traffic across different servers, so your IP address and location remain protected. It is also important that this tool is based on a strict no-log policy, so no data is collected and cannot be leaked or made available to first or third parties. If you want to feel safe on the internet, a combination of a secure web browser and a Private Internet Access VPN will help you.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
