QNBQW virus Removal Guide

What is QNBQW ransomware?

QNBQW — a ransomware virus that blocks access to your data

QNBQW ransomware virusQNBQW ransomware is a crypto-virus that demands ransom QNBQW is a crypto-virus that came to researchers’ attention at the beginning of June 2018. It uses AES-256 cryptography to make files on the affected computer useless. This ransomware activity is for money extortion because virus developers demand the ransom once all files are locked with .qnbqw extension. Immediately after this, the virus places a ransom message in Notice.txt file.

Type Ransomware
Danger level High. Encrypts data and demands ransom
Email qnbqwqe@protonmail.com
Ransom note Notice.txt
Extension .qnbqw
Distribution Insecure email attachments
Elimination Best tool for ransomware removal is FortectIntego

Ransom message often contains information about preferred payment method and ransom amount, instructions for creating accounts on cryptocurrency[1] sites and other file decryption offers. This time QNBQW virus developers have nothing much to say to the victims. Information in the ransom note only contains a contact email “qnbqwqe@protonmail.com” and victims ID, which includes almost 700 characters:

Your files is encrypted using the WAS the AES-256 algorithm. Write me to e-mail: qnbqwqe@protonmail.com to get your decryption key.
USERKEY Your: op1g5NxV…

As you can see, there is no information about ransom amount. Therefore, victims of QNBQW might be asked to transfer a different sum of money based on how fast they contact criminals or the size of the encrypted files. However, we do not recommend contacting them in order to avoid further possible problems.

QNBQW removal should be done quickly because any contact between victims and cybercriminals cannot give positive results. These virus developers often ignore their victims after the payment is done and they might have no alleged decryption tool. All of this is done to only extort money from you. So you need to focus on the virus elimination and just after your system is clean think about file recovery.

Virus researchers form Virusi.hr[2] highly recommend using professional tools for ransomware elimination. Our team suggests victims to remove QNBQW ransomware using FortectIntego, but feel free to chose any other proffesional software. Using security program is the best way to ensure that any ransomware related programs and tools are deleted properly. If you insert an external drive with backup files to a computer that is not cleaned yet you can lose your data permanently.

Emails can have harmful attachments: be careful before opening them

You probably already spotted those emails from suspicious addresses or containing questionable information. Spam email box often has legitimately looking letters that came from companies you might know but do not use. These letters may seem genuine and contain safe-looking files like Word documents. But these might be filled with malicious macro commands [3] and install malware on the system unknowingly.

Being careful with received emails is essential. Especially from the spam/commercial box. Delete them and never open those attachments. Opening and purchasing something from those ads can lead to infections and more significant problems with your PC.

To make sure that your files are safe from malware, you need to create backups. If you have your most important files on another drive you can restore them after an attack.

Viruses come with other malicious tools and programs, so you need to do a full system scan to get rid off all of them. If you leave any of those threats on your computer, you cannot be sure that ransomware would repeat the attack.

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.
