Dis virus Removal Guide

What is Dis ransomware?

Dis ransomware – a cryptocurrency extorting cyber infection that locks all personal files

Dis ransomwareDis ransomware is a data-locking computer virus that asks for money in exchange for a decryption key

Dis ransomware is a computer infection that encrypts all personal data, renames it, and generates ransom notes to demand money for decryption. If your original filenames are appended with id-(user ID).[decrypt@disroot.org].dis extension that means your computer is infected. So if your files were affected by this virus, each of them would have this or a similar look:

  • picture.jpg.id-C482E416.[decrypt@disroot.org].dis

Another clear indication of Dis virus intrusion is the appearance of the FILES ENCRYPTED.txt text file and a decrypt@disroot.org pop-up window. These are ransom notes containing instructions on establishing contact with the assailants and regain access to your locked files.

If you spotted any of these indications, then you came to the right place. This article provides a detailed summary of the Dis ransomware virus, its spreading techniques, how to avoid them, and, most importantly, how to eliminate it from infected devices automatically. While there is no working decryption tool for Dharma family variants, there are some alternative methods that could help you to recover your files – check the details below.

Dis virus derives from a well-known ransomware family. Cryptoviruses from it was first spotted in 2016, but the group got really active from the first quarter of 2019. Since then, new variations are introduced each week. Here are a few examples of the latest ones:

All these versions have many similarities. All of them rename the encrypted files with a complex triple extension that consists of a unique appointed user ID, cybercriminals' contact email address, and a few random characters in the end that end up as the name of the ransomware.

Another similarity is that most of the ransom notes are almost identical – only the email address differs. Dis ransomware virus developers send this message in their FILES ENCRYPTED.txt ransom note:

all your data has been locked us
You want to return?
write email decrypt@disroot.org

Dis ransomware virusDis virus is a ransomware-type virus

This message is displayed in the ransom pop-up window:

YOUR FILES ARE ENCRYPTED
Don't worry,you can return all your files!
If you want to restore them, follow this link:email decrypt@disroot.org YOUR ID –
If you have not been answered via the link within 12 hours, write to us by e-mail:decrypt@disroot.org
Attention!
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

The purpose of these notes is to intimidate victims into complying with the criminals' demands and contacting them immediately. We highly advise against any of these actions. Instead, victims should remove Dis ransomware from their devices and forget about this misfortune.

We recommend removing the infection with professional anti-malware software such as SpyHunter 5Combo Cleaner or Malwarebytes that can automatically accomplish this task. Manual Dis ransomware removal is also possible, but it requires extensive knowledge, so we recommend sticking to the automatic solution.

As a rule, malware infections make alterations to system files and settings, which lead to various system irregularities like crashing, BSOD, freezing, performance loss, and so on. Cybersecurity specialists at SenzaVirus.it[1] recommend using the ReimageIntego tune-up tool to repair the system issues.

Cautiousness helps prevent malware infections

Cybercriminals are constantly developing new, more improved malware and ways to distribute it. There are various kinds of malware (Trojans, ransomware, keyloggers, etc.), and it's spread using different techniques (Remote Desktop Protocol attacks,[2] drive-by downloads,[3] deceptive ads, etc.).

Two of the most popular ways to distribute malware are email spam and file-sharing platforms. We've all received spam emails in our lives. Some of it is harmless, while others might contain virus payload files hidden in the email attachments or hyperlinks in the message.

File-sharing platforms, such as the most popular torrent portals, are a hotbed for malware. Cybercriminals exploit the lack of end-to-end security by offering to download their creations camouflaged as game cracks, pirated expensive software, and other eye-catching stuff.

To evade malware and potentially unwanted programs (adware, browser hijackers, scareware, etc.), please don't open any attachments and links in emails that look at least slightly suspicious. Also, please refrain from using torrent sites are they are crawling with all kinds of malware.

Instructions for Dis ransomware removal with anti-malware software

First of all, if you have an anti-malware app but your device got infected, that means you have to replace it with a trustworthy tool like SpyHunter 5Combo Cleaner or Malwarebytes. These apps are capable of preventing such attacks in the future and can take on Dis ransomware removal.

Dis virus detectionDis ransomware can be stopped by multiple security programs before it manages to encrypt files, so never ignore warnings!

Cryptoviruses can disable anti-malware tools. If that happened and the virus can't be deleted, you must try to eliminate it in Safe Mode with Networking. Please see our detailed guide below this chapter and follow the step-by-step instructions if you don't know how to do that.

Once you remove Dis ransomware from an infected device, you should take care of corrupted system files and settings. For this task, we highly recommend using the ReimageIntego system repair tool as it will fix all issues with a push of a button.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
