NTK virus Removal Guide

What is NTK ransomware virus?

A ransomware dubbed NTK is not as dangerous as it seems to be

NTK virus is a screen-locking Trojan horse[1], which earns the name of ransomware[2] due to its ability to block access to the computer and demand a ransom from the computer owner or user. Just like any other ransomware virus, it is a vicious software that functions as an extortion[3] tool. NTK Screenlocker virus displays a full-screen message for the victim, and at the moment NTK ransomware supports French language only. Upon installation, it runs itself as a Winban.exe file, also adds shady entries into Windows Registry[4] and ensures that it stays on the computer system for a long time. However, despite efforts that the developer of NTK malware put into it, the ransomware can be removed with anti-malware tools like FortectIntego or Malwarebytes easily. The screen-locking window contains a message, which says:

You got pOwned by NTK

Ton PC est bloque 🙂 Si tu veux pouvoir le reutiliser, suis les instructions ci-dessous.

  1. Appuyez sur Afficher coordonnees
  2. Envoyez un mail et mettre en objet : Code UTK

Afficher coordonnees

NTK ransomware virusResearcher shows the text that NTK ransomware displays for the victim.

In short, virus’ author who names itself as NTK, says that the victim has to click on “Afficher coordonnees” button (display coordinates), which reveals cyber criminals’ email address. They will then ask you to pay a ransom to get access to your own PC, but obviously, you shouldn’t pay it. If you enter this code – 15s4e56dsjdhfy87 into the provided field, you would be redirected to another panel that explains how to remove the virus and unlock access to the computer. However, since we are going to provide you these instructions for free, you do not need to waste your time contacting cyber criminals, or, even worse, spending your hard-earned money by paying ransoms[5]. You can find the guide on how to remove NTK malware below this article. Do not forget to use professional anti-malware tools after NTK removal to scan your system and find any additional threats that you may have installed in the past.

How does this ransomware disseminate?

You do not want to be deceived by cyber criminals again, don’t you? If so, please read this paragraph attentively. Please try to avoid opening emails that come from unsolicited and unknown individuals or companies. Here are some tips how you can identify malicious emails:

  1. Look at sender’s email address. Check it on Google if you doubt that it comes from a trustworthy person/company.
  2. If you have any doubts about an individual email message, do not open files attached to it, nor links included in the letter.
  3. Check what kind of link appears in your browser’s bottom left corner as you hover over the message or underlined text including hyperlinks. If these URLs appear to be very long and suspicious, do not click on anything!
  4. Ransomware can also be delivered to you via exploit kits or compromised websites, so to prevent such attacks, we suggest keeping your programs up-to-date and installing an anti-malware program on the system.

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.
