Fopa file virus (Decryption Methods Included)
Fopa file virus Removal Guide
What is Fopa file virus?
Fopa ransomware is a cyber infection that might result in complete data compromise
Once files get locked and the ransom note delivered on the screen, malware is done encrypting data
Fopa ransomware is a virus that attacks Windows computers by using various infiltration methods. Once inside, it uses an encryption algorithm to lock up all documents, archives, videos, music, and other files, adding .fopa extension to them. After that, ransomware delivers a ransom note _readme.txt text file, which includes instructions on how to recover the encrypted data.
According to Fopa virus authors, victims need to contact them via email@example.com, firstname.lastname@example.org email, and provide their personal ID. Once that is done, users should receive further instructions to proceed with the payment, provided in bitcoin cryptocurrency. Nonetheless, we do not recommend contacting the attackers because they might not deliver the required decryption tool. Check out the alternative methods we provide below instead.
Fopa ransomware is a cryptovirus that belongs to a malware family known as Djvu ransomware. This malware encrypts all the important files on a Windows computer and restricts access to them. While it is true that Fopa virus files require a unique decryption key to unlock them, experts recommend not paying the ransom, as cybercriminals might not keep their promises, resulting in financial losses.
Especially when the family is known for creating new versions that are no longer decryptable. Criminals controlling the behavior can create various issues and are evolving. In this article, we will explain how to get rid of malware and use alternative methods for data recovery.

Details on the infection and the virus family
Fopa is a type of virus that is classified as ransomware. These threats are known for accessing user machines without permission and encrypting all files on them. This way, cybercriminals behind the attack can ask for a ransom payment in return for a unique key.
Fopa ransomware – a computer infection that encrypts all personal files found on the machine and marks them with the unique extension, restricting access to them. Malware then drops a ransom note with a direct message from criminals, which claims that the only way to securely return data is by paying a ransom – it should be delivered using digital bitcoin currency.
The criminal group even offers a discount to trick people or scare them into paying the ransom amount of $980 or $490 in the form of Bitcoin cryptocurrency. These threat families nowadays even use triple or double extortion methods to ensure that people are paying them and criminals can make money from victims worldwide.
This virus derives from a well-known family Djvu/STOP, which was first spotted in 2019 and since then released multiple variants, including Iiof, Qbaa, Vyia. In this article, we will provide alternative methods for .fopa file recovery and safe ways of deleting the infection from a Windows computer.
File-locking can be quick, so make sure to remove the threat to save what is left
Decryption possibility is slim, but there for some users
The family of Djvu viruses is one that has been known for years now, and it's no stranger to threats. The new versions come out each week with different names or infection methods, which makes tracking them down difficult as well. The newer types of encryption are more secure than their predecessors because they affect how you can decipher data.
However, both offline keys and online ones may be in use. There's a difference between them that determines the recovery success, though. When servers cannot communicate with the virus, offline ids become necessary, which means each version has one ID used by all devices affected by it. The different versions of Dis are created when the file virus relies on online IDs. This is the case with Fopa ransomware.
You can try to check if the version that you encountered is possible to decrypt or not. The tool below is still working sometimes. This file virus might not connect to servers and use offline ids for your device, so it's important to know how these work before starting anything else!
If your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.
Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.
- Download the app from the official Emsisoft website.
- After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
- If User Account Control (UAC) message shows up, press Yes.
- Agree to License Terms by pressing Yes.
- After Disclaimer shows up, press OK.
- The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
- Press Decrypt.
Removing the threat should be a priority
The infection is created with the main purpose of getting funds from victims, so there is no guarantee that payment transfer could help with file recovery. However, consider the threat as dangerous and extremely malicious. You need to remove the Fopa file virus first before you even attempt file recovery using backups or third-party programs for data recovery.
Removing the infection is not the same as decrypting data or repairing system issues, so you need anti-malware tools like SpyHunter 5Combo Cleaner or Malwarebytes and a full system scan. Detection rates can indicate that VA engines are successful in such operations, so you can eliminate the threat and properly clear the machine from any leftovers of the virus.
However, there are additional issues related to the infection of this sort because Fopa ransomware can damage processes, disable programs, features to keep the infection running on the machine and trigger the particular background processes. This program is capable of damaging various programs and keeping them from running to ensure that Fopa virus and other malware are not affecting the machine.
Therefore, we highly recommend using a one-of-a-kind, patented technology of RestoroIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.
- Download the application by clicking on the link above
- Click on the ReimageRepair.exe
- If User Account Control (UAC) shows up, select Yes
- Press Install and wait till the program finishes the installation process
- The analysis of your machine will begin immediately
- Once complete, check the results – they will be listed in the Summary
- You can now click on each of the issues and fix them manually
- If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.
Getting rid of Fopa file virus. Follow these steps
Important steps to take before you begin malware removal
File encryption and ransomware infection are two independent processes (although the latter would not be possible without the former). However, it is important to understand that malware performs various changes within a Windows operating system, fundamentally changing the way it works.
IMPORTANT for those without backups! →
If you attempt to use security or recovery software immediately, you might permanently damage your files, and even a working decryptor then would not be able to save them.
Before you proceed with the removal instructions below, you should copy the encrypted files onto a separate medium, such as USB flash drive or SSD, and then disconnect them from your computer. Encrypted data does not hold any malicious code, so it is safe to transfer to other devices.
The instructions below might initially seem overwhelming and complicated, but they are not difficult to understand as long as you follow each step in the appropriate order. This comprehensive free guide will help you to handle the malware removal and data recovery process correctly.
If you have any questions, comments, or are having troubles with following the instructions, please do not hesitate to contact us via the Ask Us section.
It is vital to eliminate malware infection from the computer fully before starting the data recovery process, otherwise ransomware might re-encrypt retrieved files from backups repeatedly.
Restore Windows "hosts" file to its original state
Some ransomware might modify Windows hosts file in order to prevent users from accessing certain websites online. For example, Djvu ransomware variants add dozens of entries containing URLs of security-related websites, such as 2-spyware.com. Each of the entries means that users will not be able to access the listed web addresses and will receive an error instead.
Here's an example of “hosts” file entries that were injected by ransomware:
In order to restore your ability to access all websites without restrictions, you should either delete the file (Windows will automatically recreate it) or remove all the malware-created entries. If you have never touched the “hosts” file before, you should simply delete it by marking it and pressing Shift + Del on your keyboard. For that, navigate to the following location:
Restore files using data recovery software
Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.
While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.
Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:
- Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
- Only attempt to recover your files using this method after you perform a scan with anti-malware software.
Install data recovery software
- Download Data Recovery Pro.
- Double-click the installer to launch it.
- Follow on-screen instructions to install the software.
- As soon as you press Finish, you can use the app.
- Select Everything or pick individual folders where you want the files to be recovered from.
- Press Next.
- At the bottom, enable Deep scan and pick which Disks you want to be scanned.
- Press Scan and wait till it is complete.
- You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
- Press Recover to retrieve your files.
Create data backups to avoid file loss in the future
One of the many countermeasures for home users against ransomware is data backups. Even if your Windows get corrupted, you can reinstall everything from scratch and retrieve files from backups with minimal losses overall. Most importantly, you would not have to pay cybercriminals and risk your money as well.
Therefore, if you have already dealt with a ransomware attack, we strongly advise you to prepare backups for future use. There are two options available to you:
- Backup on a physical external drive, such as a USB flash drive or external HDD.
- Use cloud storage services.
The first method is not that convenient, however, as backups need to constantly be updated manually – although it is very reliable. Therefore, we highly advise choosing cloud storage instead – it is easy to set up and efficient to sustain. The problem with it is that storage space is limited unless you want to pay for the subscription.
Using Microsoft OneDrive
OneDrive is a built-in tool that comes with every modern Windows version. By default, you get 5 GB of storage that you can use for free. You can increase that storage space, but for a price. Here's how to setup backups for OneDrive:
- Click on the OneDrive icon within your system tray.
- Select Help & Settings > Settings.
- If you don't see your email under the Account tab, you should click Add an account and proceed with the on-screen instructions to set yourself up.
- Once done, move to the Backup tab and click Manage backup.
- Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
- Press Start backup.
After this, all the files that are imported into the above-mentioned folders will be automatically backed for you. If you want to add other folders or files, you have to do that manually. For that, open File Explorer by pressing Win + E on your keyboard, and then click on the OneDrive icon. You should drag and drop folders you want to backup (or you can use Copy/Paste as well).
Using Google Drive
Google Drive is another great solution for free backups. The good news is that you get as much as 15GB for free by choosing this storage. There are also paid versions available, with significantly more storage to choose from.
You can access Google Drive via the web browser or use a desktop app you can download on the official website. If you want your files to be synced automatically, you will have to download the app, however.
- Download the Google Drive app installer and click on it.
- Wait a few seconds for it to be installed.
- Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
- Click Get Started.
- Enter all the required information – your email/phone, and password.
- Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
- Once done, pick Next.
- Now you can select to sync items to be visible on your computer.
- Finally, press Start and wait till the sync is complete. Your files are now being backed up.
Report the incident to your local authorities
Ransomware is a huge business that is highly illegal, and authorities are very involved in catching malware operators. To have increased chances of identifying the culprits, the agencies need information. Therefore, by reporting the crime, you could help with stopping the cybercriminal activities and catching the threat actors. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Additionally, providing documents such as ransom notes, examples of encrypted files, or malware executables would also be beneficial.
Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:
- USA – Internet Crime Complaint Center IC3
- United Kingdom – ActionFraud
- Canada – Canadian Anti-Fraud Centre
- Australia – ScamWatch
- New Zealand – ConsumerProtection
- Germany – Polizei
- France – Ministère de l'Intérieur
If your country is not listed above, you should contact the local police department or communications center.
Manual removal using Safe Mode
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.
Windows 10 / Windows 8
- Right-click on Start button and select Settings.
- Scroll down to pick Update & Security.
- On the left side of the window, pick Recovery.

- Click Restart now.
- Select Troubleshoot.
- Go to Advanced options.
- Select Startup Settings.
- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.
Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.
- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.
- Go back to the process, right-click and pick End Task.
- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.
Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.
- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
- Pick Clean up system files.
- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
After you are finished, reboot the PC in normal mode.
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Fopa file and other ransomwares, use a reputable anti-spyware, such as RestoroIntego, 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.
