What is ViACrypt ransomware virus?

ViACrypt makes the best of Windows RASMAN functionality

ViACrypt virus

ViACrypt virus functions as new crypto-ransomware[1] which encrypts victims’ personal files using an exquisite RSA-1024 algorithm, adds .via extensions to files and drops a ransom note called Your system has been encrypted! please read further instruction!.txt on the computer’s desktop to demand a ransom payment.

That may be a lot to take in. So, let’s start from the beginning.
ViACrypt belongs to a group of very dangerous computer viruses which prevent victims from accessing their personal files by enciphering their contents using military-grade encryption algorithms.

The threat begins the system infiltration by deploying its dropper file called crawl.exe in the %APPDATA% folder of the PC. It then makes changes to Remote Access Connection Manager (RASMAN) [2] settings to establish a connection to the secret hacker server. Later on, the rest of the payload files get downloaded on the device.

Once all the crucial elements are delivered into the computer, the threat starts looking for different files to encrypt. After this process is over, it becomes virtually impossible to remove ViACrypt from the PC without any consequences. For that purpose, ReimageIntego or Malwarebytes will come in handy.

Among the files that this threat drops on the PC is the ransom note and the public key used for the data decoding called your_encryption_public_key.rkf.

The ransom message contains the following message:

Your system files has been encrypted and only way to recover them is by purchasing unlocking key.
Steps to gain access for files:
1) Please follow this page: xxxx://
2) Upload your public encryption key
3) Download decryption key
4) Drag and drop key on crawl.exe
5) Wait for files to be unlocked in background

Consider whether following these instructions is a convenient option to you. This data recovery method is suggested by perpetrators who have encrypted your PC in the first place, so it is highly risky to trust them with its recovery.

In fact, cyber security experts recommend performing ViACrypt removal instead and wait for some safer data recovery solution to come about. Professional malware investigators often come up with free ransomware decryption tools, so it is likely that one can be invented for this malware as well.

Currently, the malware is very active in Latvia [3]. Even the ransom payment site is written in this language.

Things determining crypto-malware infiltration process

Main vectors of ViACrypt ransomware distributions are infectious spam email attachments and compromised online downloads. We should note that ransomware is more commonly infects outdated operating systems which no longer receive security patches from the vendor. Sp, the main factors that help ransomware to infiltrate PCs are the following:

  • Carelessly downloading software from random websites
  • Using outdated and unsupported operating system
  • Keeping outdated software installed on the computer
  • Downloading and opening suspicious email attachments
  • Employing illegal endpoint security utilities to protect your device

If you find yourself doing any of these things, make sure you fix the situation without further delay, because continuing these faulty activities may cost you your files. You can be certain that the hackers behind ViACrypt malware will exploit these vulnerabilities.

Choosing the right software for ViACrypt termination

When infected, there is nothing you should prioritize more than ViACrypt removal computer. Don’t start from data decryption — your files will be repeatedly encrypted or destroyed completely if the virus runs on the computer during recovery.

To be safe, launch a professional antivirus software and allow it to scan your entire system looking for malicious ransomware components. It should take the virus a few minutes to remove ViACrypt virus and for you to return to the safe computer using again.

Getting rid of ViACrypt virus. Follow these steps

Manual removal using Safe Mode

If you need an advice on how to decontaminate this threat, you will find it below. This will help your antivirus to run a system scan without being interrupted by the ransomware.

Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove ViACrypt from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by ViACrypt, you can use several methods to restore them:

Using Data Recovery Pro to recover files encrypted by ViACrypt

Below you will find all the necessary information on how to recover files encrypted the ransomware. We can't promise it will be 100% effective, but you can give it a try

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by ViACrypt ransomware;
  • Restore them.

Travel in time with the help of Windows Previous Versions feature

Do you dream of turning back time and backing up your files before the virus has hit your PC? Well, Windows Previous Versions feature may make it possible. This tool will allow you to restore previously saved versions of your files if you had the System Restore feature enabled on your PC pre-attack.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer: file recovery with the assistance of Volume Shadow Copies

Check whether the Volume Shadow Copies of the encrypted files are in tact and start data recovery with ShadowExplorer.

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from ViACrypt and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
