AiraCrop ransomware virus. How to remove? (Uninstall guide)

removal by Lucia Danes - - | Type: Ransomware

What do we know about AiraCrop ransomware virus so far?

AiraCrop virus which might be detected as Win32/Filecoder.AiraCrop.A Trojan is yet another cyber infection which can be added to the expanding family of ransomware viruses. This virus is completely new, so the experts are still figuring out whether it is an original creation or a version of some more major ransomware. It is speculated that AiraCrop malware might be related to CrySiS, but this theory does not have enough evidence to be confirmed. Nevertheless, there is some information that we already know about this threat. Ransomware victims report that the virus encrypts files and pins .airacropencrypted! extension to them. Such files immediately become inaccessible and sadly, deleting the extension, changing them to the regular ones or even eliminating the virus from the computer does not help to regain this access. In fact, it is unlikely that you will manage to recover your files at all. Of course, you can apply emergency techniques that we have provided at the end of the article, but you should not expect a miracle. It might be that you will simply have to admit that the hackers have outsmarted you and settle with the AiraCrop removal. To make this process less time-consuming and more secure, we recommend employing automatic antivirus utilities such as Reimage for the task.

Illustration of the AiraCrop virus

Another source of information that we have about AiraCrop ransomware is its ransom note. Although we don’t know for sure whether it is the final and the only version of the note, we think it is useful to discuss it. You can see this note below:

Encrypted Files!

All your files are encrypted. Using encryption AES 256-bit and RSA-2048-bit.
Making it impossible to recover the files without the correct private key.
If you are interested in getting is key, and retrieve your files
visit one of the links and enter your key;

As you can see, the note is rather obscure. The criminals do not provide any detailed information such as the amount of the payment nor the deadline for it to be issued. However, we can see that like the majority of ransomware viruses AiraCrop uses the anonymous TOR network to collect payments. We can also gather that the criminals use military grade AES 256-bit and RSA-2048-bit encryption algorithms that are also favored by such ransomware giants as Locky and Cerber ransomware. This only proves that these hackers are not playing games and will not give back your files that easy. And you should not try satisfying their greediness either. Remove AiraCrop from your computer without giving in to the hacker’s plan and, hopefully, this will help decrease the hackers’ motivation to create similar malware at least a little.

How does this virus travel across the Web?

Most likely, the virus is carried around by a malicious spam campaign that makes sure this malware enters computers without the victims even realizing it. Typically, malware infected files will end up in the “Spam” section of your email, but beware that they may obfuscate the malicious files and slip them through the security filters straight into your inbox. In such a case, it is beneficial to know how to recognize such malicious emails. The first thing to pay attention to is the sender — you should not receive emails from unknown third-parties unless you have provided them with your email yourself. Otherwise, it is either a commercial spam or malware. You probably do not want to deal with any of these. You should be especially careful with emails that feature attached documents or links. Investigate these attachments before opening them and double-check whether they were really meant for you.

AiraCrop removal options:

Like any other malicious infection, AiraCrop virus should be eliminated from the affected computer as soon as possible. Professional anti-malware tools, such as Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus should be used for this purpose, but some part of the AiraCrop removal might have to be carried out manually. This might be necessary if the ransomware interferes with the antivirus utility and tries to block it from scanning the system. The guidelines for the virus decontamination are provided below the article. After you complete them and remove AiraCrop from your computer, you can proceed to the process of data recovery. A few methods for data recovery techniques are also presented below.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove AiraCrop from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If you came here for the AiraCrop decryption tool, we are sorry to let you down. Such a tool does not exist yet, though the experts are constantly working on ransomware decryptors. Though you should not panic just yet because below you will find a couple of methods that might help recover some of your files.

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

What are the benefits of recovering data with Data Recovery Pro?

Data Recovery Pro is an automatic data recovery tool, so the major benefit is that it is more or less effortless. Though we cannot guarantee that the program successfully recreates all of your data, it is worth giving it a try. Follow the instructions below to get started:

How can Windows Previous Versions feature be used to recover the locked data? 

Windows Previous Versions feature is not specifically used for bypassing ransomware encryptions, but it can be used to recover individual files from a System Recovery backup. Learn how to do that below.

  • 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”.

Will ShadowExplorer recovery your files?

Malicious viruses usually delete Volume Shadow Copies from the infected computer to encumber the file recovery. Nevertheless, if AiraCrop does not delete them, you stand a good chance in recovering them using ShadowExplorer. Instructions bellow show how to use this tool properly.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • 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 AiraCrop and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
