Nacro virus Removal Guide

What is Nacro ransomware?

Nacro ransomware is a file locking virus that is spread via malicious torrent files

Nacro ransomwareNacro ransomware is a file locking virus that locks all your data and demands $980 ransom in Bitcoin for the decryption tool

Nacro ransomware is crypto-malware that was fist spotted in mid-August 2019. Just as dozens of other STOP/Djvu ransomware variants, it enters the computer and encrypts all documents, pictures, databases, videos and other personal files with the help of AES or another encryption algorithm. From that point, victims cannot access their files that are marked by .nacro extension and begin to look for solutions for a rather difficult situation.

After file encryption, Nacro ransomware drops a ransom note _readme.txt, contents of which are almost identical to previous versions of the same family – Cosakos, Besub, Bopador, and others. The message from the threat actors states that victims have to contact them via gorentos@bitmessage.ch, gorentos2@firemail.cc, or @datarestore (Telegram) and pay $980 ransom in Bitcoin in order to receive the decryption tool.

While there are little chances of recovering data without the promised key, paying the ransom is highly discouraged by security experts,[1] as the possibility of getting scammed is still there. Instead, users are encouraged to proceed with Nacro ransomware removal and using alternative tools and the provided STOPDecrypter to retrieve the locked data.

Nacro ransomware was spotted being spread via malicious torrent files from KickAssTorrents, namely KMS which is used to activate the illegal versions of Windows OS and MS Office suite. Nevertheless, it is known that STOP ransomware authors use multiple other delivery methods, including:

  • Exploit kits[2]
  • Software vulnerabilities
  • Unprotected RDP
  • Web injects
  • Fake updates
  • Spam emails, etc.

Besides encrypting all personal data, Nacro virus changes crucial Windows functions to be able to run on the system without interruptions. For example, it deletes Shadow Volume Copies[3] in order to make the recovery process much more complicated. Additionally, it modifies Windows Registry to be able to run as soon as the host machine is booted.

The ransom note that Nacro ransomware drops states the following:

As we previously mentioned, paying people behind Nacro virus is highly risky, as they might simply ignore you and never send you the decryption key that is required for file recovery. Additionally, they might send you a malicious file that would infect your machine with other malware, such as a trojan, rootkit, or other.

Nacro ransomware virusNacro ransomware is a cryptovirus that spreads via malicious software cracks downloaded from torrent sites like KickAssTorrents

Thus, if you were unlucky and got infected, should remove Nacro ransomware first and then explore the file recovery options. While they are quire minuscule if no backups are available, it might still be possible to decode the data in other ways.

For Nacro ransomware termination, use reputable anti-malware software and then scan your system with ReimageIntego to fix the virus damage.

Do not download pirated software or its cracks – ransomware will immediately lock your files as soon as you open the malicious executable

Pirated software and cracks have been extremely popular over the years, as it allows users using software that would otherwise be paid for. However, not only is this behavior illegal, but it can also compromise personal safety. Nevertheless, tools like KMSpico and similar have seen tremendous popularity over the years, as they are used for most popular software cracking.

Crack tools are often flagged by anti-malware software by default, because of the activity that it performs. It initiates modifications that are typical to malware – changing the way the software operates. For that reason, checking if the crack is actually harmful and carries malicious payload is almost impossible.

Therefore, refrain from downloading pirated programs, as well as cracks/keygens. Additionally, install anti-malware software, regularly update your OS, avoid spam email attachments, use secure passwords, and always back up your data!

Remove Nacro ransomware to protect your incoming files from being locked

Nacro ransomware removal should not be very complicated, as long as you employ reputable anti-malware software. There are plenty to choose from, although be aware that all the AV vendors might not recognize new virus variants. Thus, you might need several security tools before you can get rid of Nacro virus. Note that the malware possesses various capabilities, and might sometimes block your security application. In such a case, enter Safe Mode with networking as explained below and perform a full system scan from there.

Nacro ransomware encrypted filesUnfortunately, but once Nacro ransomware encrypts the files located on the hard drive, restoring them without backups is quite difficult

Once you remove Nacro ransomware, you can attempt to recover your files. With backups, there should be no problems – simply connect your external device or access virtual storage and copy the data over. However, with no backups, things get a little more complicated, and the chance of recovery slims down. You can try STOPDecryptor or use alternative solutions instructions of which we provide below.

Bonus: Recover your data

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

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

Data Recovery Pro might be useful when trying to recover .nacro locked files

While Data Recovery Pro is not originally created to decode encrypted files, it might be able to restore them in a different way.

  • 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 Nacro ransomware;
  • Restore them.

Make use of Windows Previous Versions feature

Windows Previous Versions method can only be applied if you had System Restore enabled before your computer got infected with ransomware.

  • 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”.

In some cases, ShadowExplorer will recover all your files

ShadowExplorer would be the ultimate answer if Nacro ransomware failed to delete Shadow Volume Copies from the system.

  • 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.

Make use of specially crafted decryption tool

If the encryption was performed while your computer was offline or the malware failed to connect to its remote server, you can use STOPDecrypter [download link] to retrieve the locked data.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Nacro 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.
