How Yogynicof ransomware behaves
From our report of Jun 2020 · not reviewed since
Yogynicof ransomware is a cryptovirus that generates 20 HTML notes on the host machine
Yogynicof ransomware is a virus that encrypts 122 extensions on the machine using AES + RSA encryption algorithm.
Upon that, most of the files stored on the targeted Windows machine get locked and replaced with consecutive numbers 1,2,3,4,5,6, etc. To ensure that the user understands that the system is taken hostage, the virus generates 20 HTML files from Read-me!
0.html to Read-me! 20.html on the desktop. Each of the ransom note redirects to the Yogynicof ransom page on the Internet Explorer web browser where victims get the basic information on the attack and ransom payment conditions.
The crooks behind the Yogynicof ransomware offer people to purchase the decryptor for $500. However, this price is applied to those who respond within 48 hours. It's yet unknown whether the virus permanently restricts people's access to their personal files if the payment is not transferred with the dedicated period or the ransom size is increased.
According to criminals, victims have to make the payment in Monero (XMR) cryptocurrency via the [payment address omitted] Monero Wallet and the write an email to yogynicof@protonmail.com indicating unique ID number.
Yogynicof ransomware virus encrypts to files on the infected machine using a combination of AES and RSA encryption algorithm. It is capable of encrypting 122 types of extensions, including MS Office documents, OpenOffice, PDF files, text files, databases, images, photos, archives, and other important files. The extensions mainly targeted by this virus are the following:
The Yogynicof virus encrypted files, unlike with most other ransomware viruses, do not get a unique file extension. Instead, they are completely renamed using a simple numbering scheme starting with 1 and increase the sequence depending on the number of detected files.
Besides, it seems that developers of the Yogynicof virus are afraid of victims not to notice the presence of the ransomware. For this purpose, they programmed the virus to generate 20 identical HTML files dubbed as Read-me! 1 .html, Read-me! 2 .html, Read-me!
3 .html, and so on. These so-called ransom notes automatically open the web browser and display a pre-default page that guides the victims through the ransomware maze. The victim is expected to pay Monero cryptocurrency for $500 and transmit the money to criminals via [payment address omitted] Monero wallet.
After that, they are supposed to inform criminals about the transfer via email (yogynicof@protonmail.com), though the message necessarily has to contain a personal ID number that is given on the HTML file.
A full text of the Yogynicof ransom note:
However, files encrypted by Yogynicof ransomware is just a peak of an iceberg. This dangerous virus is programmed to initiate aggressive alterations of the Windows OS.
One of the most malicious processes run by this malware is github.exe . Upon infiltration, it automatically opens files on C:\WINDOWS\system32\ and injecting malicious scripts onto them. Based on the analysis, the virus targets these files:
On top of that, it can delete the content from Windows registries, especially located in \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\ directory. Therefore, if your files have been encrypted, we would strongly recommend you to think about an immediate Yogynicof removal instead of ransom payment.
Paying the ransom is pointless because there's a high risk of being deceived. No one can guarantee that criminals will provide you with a functional decryption tool, thus leaving you with empty pockets and restricted from the usage of personal files.
Luckily, it's not difficult to remove Yogynicof ransomware from the machine. You should learn how to restart the system into Safe Mode and then launch the antivirus program. However, make sure to use an updated AV version and set it to perform a thorough system scan.
NOTE: before Yogynicof ransomware removal it is advisable to make copies of the encrypted files to prevent permanent file loss. Use external hard drive, USB stick, or cloud storage. This particular ransomware is under investigation right now as it's a novel virus with exceptional traits. It's very likely that cybercriminals will detect some flaws in the encryption model allowing them to create a functional free decryption tool.

Ransomware-type viruses can be spread via malicious files within spam emails
File-encrypting ransomware virus is typically disguised by highly obfuscated files.
These files can be injected into spam email attachments, fake software updates, cracks, keygens, and whatnot. Often such files are recognized by AV tools; however, it must be fully updated. Nevertheless, there are thousands of malicious executables that manage to bypass security software without being noticed. Therefore, it's very important for people to be careful when downloading anything on their machines, clicking on ads, links, or any online content.
Nevertheless, the biggest risk to get a ransomware virus is to download pirated software, cracks, and keygens. Millions of people download pirated software for unlocking additional features of paid software without evaluating the risks. At the moment, Reddit and other forums keep reporting about infected Adobe Acrobat crack spread on P2P networks. The latter appears to be infected with a Djvu ransomware virus, namely Zwer, Nlah, Usam, Tabe, and others.
Apart from software cracks, malicious cyber infections are actively distributed via spam email attachments. Therefore, if you receive an "Order Confirmation" email that contains a PDF, Word, Exel, or another format, but you haven't ordered anything, you'd better not open it as it may be infected with ransomware payload.

How to remove Yogynicof ransomware
Tools you'll need
All of these are free except where noted. Download them on a clean device if the infected PC is offline.
- A USB stick: to keep the ransom note, two or three encrypted files and screenshots off the infected PC.
- Microsoft Defender Offline: built into Windows 11 and Windows 10; scans before Windows starts, so running malware cannot hide.
- Microsoft Safety Scanner: a second, portable scanner with current signatures; each download works for 10 days.
- ID Ransomware: identifies the family from the note and one encrypted file and says whether a decryptor exists.
- No More Ransom: the free decryptors from police and security companies; check it again every few months.
- Fortect (optional): scans Windows for malware and repairs the system files and settings it damaged. The free scan is in the box above.
How to remove Yogynicof and get your files back
Work in this order.
Disconnecting comes first, removal comes before any restore, and nothing here asks you to contact the attackers.
Step 1: Disconnect the PC and unplug backup drives
Yogynicof encrypts everything it can reach, including drives and shares you connect later. Cut the network first: cable out, or Wi-Fi off from the taskbar.
Then unplug every USB stick and backup disk and pause cloud sync, so the encrypted versions do not replace your online copies. Do not reconnect any of them until the ransomware is removed from the Windows 11 or Windows 10 PC.
Windows 11: turn off Wi-Fi to take the PC offline. Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 2: Save the ransom note and confirm the family
Copy
the ransom noteand one or two files ending in.3frto a USB stick, and leave the originals where they are.From another device, upload the note and a sample file to ID Ransomware or No More Ransom's Crypto Sheriff, which name the family from the note, the extension and the file structure.
Write down the contact address and your personal ID from the note, because a decryptor or the police may ask for them.
Warning: Never contact the attackers from the infected Windows 11 or Windows 10 PC.

Step 3: Check for a free decryptor
For Yogynicof, no free decryptor is known (checked 7 October 2026). Search the family name in the No More Ransom decryption tools list and in the free decryptors of Emsisoft, Avast and Kaspersky, because new tools appear years after an attack.
Important: Keep the encrypted files even if nothing works today, and do not pay before every free option is ruled out: payment does not guarantee a working key.
Decryptors run on Windows 11 and Windows 10, but only after the ransomware itself is removed.
Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 4: Remove the ransomware before you restore or decrypt
Restoring or decrypting files while Yogynicof still runs lets it encrypt them again. Run a Full scan in Windows Security > Virus & threat protection > Scan options, then the Microsoft Defender Antivirus (offline scan).
If the ransomware blocks Windows Security, start Safe Mode with Networking and scan from there. Some families install a password stealer as well, so let both scans finish on Windows 11 or Windows 10.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 5: Look for shadow copies of the files
Open Command Prompt as administrator and run
vssadmin list shadows. If it lists copies dated before the attack, right-click a folder with encrypted files in File Explorer, choose Properties > Previous Versions, and open or restore a version from before that date.ShadowExplorer, a free tool, shows the same copies when the tab is empty or hidden. Most current families delete shadow copies, so an empty list is normal, but the check takes two minutes on Windows 11 or Windows 10.
Windows 11: vssadmin list shadows shows whether shadow copies exist. Full procedure with screenshots: Ransomware: first steps, finding a decryptor and recovering files
Step 6: Restore the files from a backup or recover deleted originals
Restore from an external backup, File History or OneDrive's version history, choosing a date before the attack. Connect the backup drive only after the scans are clean, or the ransomware encrypts it too.
If there is no backup, file recovery software can sometimes find the deleted originals, because some ransomware writes an encrypted copy and deletes the original file.
Stop writing to the drive and try recovery on Windows 11 or Windows 10 before new files overwrite the space.

Manual removal using Safe Mode
Important! →
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.

- 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
Downloads
Recycle Bin
Temporary 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):
%AppData%
%LocalAppData%
%ProgramData%
%WinDir%
After you are finished, reboot the PC in normal mode.

Get rid of the Yogynicof ransomware virus and recover the damage
Yogynicof ransomware virus focuses on locking up people's files and then collecting the money from helpless victims.
However, the damage it causes is much bigger. The file-encrypting virus unleashes tens of malicious files on the system, which aggressively alters various Windows settings, registry entries, processes, etc., which eventually can make the system crash, generate BSODs, and errors.
Therefore, if you have noticed 1,2,3,4,5,6,7, etc. tiles on your PC, all you have to do is to remove Yogynicof virus from the system without a delay. For this purpose, employ a fully-updated anti-virus application, such as or . These tools can be infringed by the virus, so if you are not allowed to launch any security tool, restart the machine in Safe Mode.
This application can help to prevent the system from crashing and encountering errors due to the changes triggered by ransomware. Finally, you can try to recover files encrypted by this ransomware. The below-given guide will help you to apply decryption steps.
[GI=method-1]Those who cannot launch AV scanner for Yogynicof ransomware removal should not worry. Rebooting Windows into Safe Mode with Networking should bypass the restrictions:
[GI=method-2]If the previous method did not help to remove malicious ransomware files, try the System Restore feature
While there's not Yogynicof decryptor available, people can try to alternative data recovery methods. We'll list them below:
However, it has a powerful scanner, which can detect some of the locked files.
Windows Previous Versions can recover files after a ransomware attack
You should enable the System restore feature first if you want to rely on Windows Previous Versions.
ShadowExplorer is the Windows feature capable of recovering files
If the ransomware is not set to remove Shadow Volume Copies, try to recover the data using the Shadow Explorer.
Although there is no way to decrypt Yogynicof files for free, we do not recommend paying the ransom. Experts are working on the decryptor for this virus, so you'd better be patient and wait for them to provide free software.
Report it and recover your files
Report it
Report the attack even if you do not expect the files back: insurers and banks ask for the report number, and police use the contacts in the note to link cases.
- United States
- FBI IC3 · FTC ReportFraud
- United Kingdom
- Report Fraud (formerly Action Fraud) · NCSC
- Australia
- ReportCyber (ASD)
- EU countries
- Europol: national reporting sites
Give the victim ID, the note and the date the files were encrypted. A business that holds personal data may also have to notify its data protection authority, in the EU within 72 hours.
Backups: the 3-2-1 rule
Keep three copies of files that matter, on two kinds of storage, with one copy offline or off-site.
A disk that stays plugged in is reached by malware like Yogynicof together with the PC; one you connect only for the backup is not.
On Windows 11, File History keeps versions on an external drive, and OneDrive keeps earlier versions of synced files. Before restoring anything, make sure the PC no longer shows files that end in .3fr and no longer open.
Setting it up step by step: 3-2-1 backups on Windows 11 and 10.
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 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 for the data restoration process.
Questions about Yogynicof ransomware
How do I open .3fr files?
You cannot open them by renaming or by choosing another program. The .3fr ending shows that Yogynicof encrypted the content, and only the matching key can reverse it. Renaming a file back to .docx or .jpg changes nothing except the icon, and it can confuse a future decryptor, so leave the names as they are.
To get the content back, use a backup, an unencrypted copy elsewhere, or a decryptor listed on No More Ransom if one exists for Yogynicof. Store the encrypted files on an external disk until then.
Can a data-recovery company decrypt my files for a fee?
Only if a decryptor already exists or the company pays the attackers for you. Some "ransomware recovery" services advertise that they can decrypt families with no known flaw; in practice they negotiate with the attackers and add their own fee. Others use the same free tools listed on No More Ransom.
Before you hire anyone, ask in writing how they will recover the files, whether they will contact the attackers and what happens if they fail. A legitimate service answers clearly. If a free decryptor exists for your family, you can run it yourself.
Is there a free Yogynicof decryptor?
We last checked on 7 October 2026, and for Yogynicof no free decryptor is known. We check No More Ransom, which collects free tools from police and security companies, and the decryptor pages of the major antivirus vendors. A working decryptor exists only when the encryption has a flaw or the keys were leaked or seized.
Ignore sites and videos that offer a "Yogynicof decryptor" for download or for a fee: these are usually scams or malware. Real decryptors are free and come from known security companies or law enforcement. Keep the encrypted files in case a tool appears later.
Should I pay the ransom?
We advise against it, and so do the FBI, Europol and national cyber agencies. Payment does not guarantee a working tool: some attackers never reply, some tools damage files, and some variants have no decryptor at all. Paying also funds further attacks and can make you a target again.
Before considering payment, try every recovery option in this guide and report the attack. Companies must involve their legal adviser and insurer, because payments to sanctioned groups can be illegal. If files are truly irreplaceable, store the encrypted copies and wait; decryptors sometimes appear later.
How did Yogynicof get on my computer?
The way Yogynicof spreads has not been documented yet, so look at your own recent activity. On home PCs, ransomware most often comes with cracked programs, game cheats, key generators and fake updates, or with an e-mail attachment that was opened. On business networks, attackers usually log in through Remote Desktop with a stolen or guessed password.
Think back to what was downloaded or installed in the days before files that end in .3fr and no longer open, and check the Downloads folder and Installed apps sorted by date. Keep anything suspicious for your report, but do not run it again.
Did Yogynicof steal my files or passwords?
We do not know yet. Nothing published so far shows data theft by Yogynicof, but the only confirmed sign is files that end in .3fr and no longer open, which says nothing about what happened before. Many current ransomware attacks copy files or run a password stealer first, so it is wise to act as if they did.
From a clean device, change the passwords that were saved in the browsers on this PC, starting with e-mail and banking, sign out of all sessions and turn on two-step verification. Watch bank statements and account activity for the next few weeks.
Is Yogynicof the same as other ransomware with a similar name?
Not necessarily. Ransomware names come from the file extension, the note or a word in the code, so unrelated families often end up with similar names, and one family can appear under several names. The difference matters: a decryptor or advice for one family does not fit another and can damage files.
Compare the ending added to your files and the exact name of the note with the summary table at the top of this guide, then upload the note and one encrypted file to ID Ransomware from a clean device. If the result names another family, follow the guide for that family instead.
Can I just remove .3fr from the file names?
You can try it on a copy, but for real ransomware it will not help. The .3fr extension is only a label; the file content has been scrambled with a key the attackers hold.
If a renamed copy opens normally, the malware only renamed files, which happens with some fake ransomware, and you can rename the rest back. If it does not open, leave the files as they are. Renaming encrypted files can confuse a decryptor later, so always work on copies.
What does the ransom note tell me about the ransomware?
Quite a lot. The file name the ransom note, the wording, the contact addresses and the format of the personal ID are typical for each family. Uploading the note together with one encrypted file to ID Ransomware or No More Ransom's Crypto Sheriff usually names the family within seconds.
That name decides your options: some families have free decryptors, some can be partially recovered, and some cannot be decrypted at all. The note's claims about stolen data should be taken seriously but not at face value.
Will Fortect remove Yogynicof?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Yogynicof, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
