How to remove Paas ransomware

Paas file virus – a Windows computer infection that leaves its victims locked out of their data

Paas ransomware is a cryptovirus developed for cryptocurrency extortion. The moment it lands on your device, it starts encrypting all personal data (videos, documents, archives, databases) and modifying system files to establish persistence. The whole process takes less than five minutes.

During the encryption, a .paas extension is appointed to the original filenames or every locked file. Their contents aren't changed, but until a necessary decryption software isn't used, you won't be able to access any of them. Threat actors behind the attack try to convince their victims that the only way to restore the data is by purchasing their decryption software.

Their instructions and demands are listed within the _readme.txt ransom note found on the desktop after the encryption. They state that if the victims reach out to them through helpmanager@airmail.cc or helpteam@mail.ch, within 72 hours, they will apply a 50% discount on the ransom, lowering it from $980 to $490.

If your computer got infected with Paas file virus, please rest assured that you don't need to forward Bitcoins to the criminals as there might be other ways to recover your files. This article contains every plausible method of infection removal, data recovery options, and ways to recover the virus damage.

The article's culprit belongs to the infamous Djvu/STOP ransomware family, which has been spewing out new variations of its infections since late 2018. Cryptoviruses from this lineage are among the most pervasive ones as they lead the stat sheets of reported ransomware attacks by a landslide.^[1]

The primary way you might have infected your computer with Paas virus is by using high-risk websites and services of file-sharing platforms, especially torrent sites. Researchers have reported^[2] that the most prominent method of spreading Djvu family ransomware is through various software cracks,^[3] including the latest games and expensive programs.

We've been helping out people who got their devices infected with various malware for more than ten years. Our cybersecurity experts and research teams provide detailed step-by-step instructions that are easy to follow, even for people who have no IT knowledge. Thus please let us walk you through this unpleasant nightmare.

Difference between old and new versions of the Djvu

This is the family that evolved over the years and started using more advanced methods when encrypting files. It was decryptable for a while, but the improved method that relies on the online victim IDs is not allowing decrypting files without obtaining a particular key for each unique victim.

When the ransomware is not connecting to the command and control server during encryption, the built-in encryption key is used. Such offline IDs generally end in t1 and can be easily identified. There are many victims with the same ID, in such cases, so many victims can get their files recovered with the particular tool. Emsisoft has released the decryptor for such versions. You can find the link and the user guide below for it.

However, .paas virus and other versions released in 2020 and later use the Online ID method. This technique allows criminals to form the unique key for each infected device. Hence, the particular victim needs to obtain a specific decryption key to recover the affected files. Criminals connect to the remote server to generate a random key.

Decryption options are limited for this reason. This is why we recommend removing the threat and saving the system before you move on t recovery methods. It is possible to wait for the decryption tool that gets developed later, so you may want to save some encrypted files and virus-related pieces on the external device and then wipe the system with anti-malware tools, so the virus is terminated.

Detailed instructions to remove Paas file virus from an infected device

If you're reading this, we take it your Windows computer was infected with the article's culprit. Well, now you can take a deep breath because the ransomware has done its deed, and there's no need to panic or make any rash decisions. We don't advise paying off your assailants as there's no guarantee that you'd receive the promised decryption software.

Moreover, the ransomware developers could use that money to expand their illegal empire by targeting more innocent people like you, developing new, more advanced versions of their malware, and researching more effective ways to distribute it.

The only reasonable action to take now is to remove Paas file virus from your device. If you didn't keep backups of your data, before you begin the removal, you have to copy all encrypted files to an offline storage device, such as a USB flash drive, SSD, or similar. We're glad you chose us to accompany you on this journey, so let's get to it.

Some infections could be removed manually, but not Paas ransomware. Thus you will need a reliable security tool for this step. We highly recommend downloading and installing either MalwarebytesMalwarebytes or SpyHunterCombo Cleaner. Both of these reliable anti-malware tools can identify, detect, and remove pretty much every cyber threat that's lurking on the internet.

Therefore after you install either of those tools, please update its virus database with the latest signatures. Then perform a full system scan and wait a couple of minutes until it's finished. When it's done, proceed with the security software recommendations on what files should be removed and do that ASAP.

That's it. Paas virus removal is finished. But that's just the beginning. However, it's worth mentioning that this ransomware could prevent you from downloading any security software or launching it. If that's the case, you will have to complete this entire step in Safe Mode with Networking. If you're unsure how to access this mode, please scroll down to the bottom of the article, where our illustrated guides are posted. Only when you remove the virus, please continue to the recovery section.

Recover Paas files and damage your computer's system has sustained

The article's culprit and its whole family make tons of modifications to system files and settings without encrypting them. It alters the Windows Registry, host files, bootup section, and other core system components. That results in the inability to use AV tools in normal Windows mode, visiting security-related pages (including 2-spyware.com), and could even lead to infection renewal.

Therefore, after you remove Paas virus and before you begin recovering data, you have to repair the damage it has caused to your system. Our recommendation is to use the time-proven FortectIntego PC repair software for this purpose, as it will fix system irregularities automatically. Only after you're done with the next step, it's safe to proceed to file recovery.

• Download the app from the official Emsisoft website.
• After pressing the Download button, click on the decrypt_STOPDjvu.exe that should show up at the bottom of your browser.
  
• If the User Account Control (UAC) alert pops up, press Yes.
• Agree to License Terms by clicking Yes.
  
  
• After the Disclaimer shows up, press OK.
• The tool should automatically locate folders affected by Paas file virus, although you can also do it by pressing Add folder:
  
• When all folders are selected, press Decrypt.
  
  

There are three possible outcomes after pressing the Decrypt button:

1. “Decrypted!” is shown when Paas file recovery is successful.
2. “Error: Unable to decrypt file with ID:” appears if the tool doesn't have the required algorithms yet, so be patient and try it out later.
3. “This ID appears to be an online ID, decryption is impossible” means that the Emsisoft decryptor is unable to help you with this version of Djvu ransomware.

If everything worked and you can use your files again – we're more than happy to help. If this step was unsuccessful, please rest assured that there are still alternative ways to recover Paas files.
