How FairWare ransomware virus behaves

From our report of Aug 2016 · not reviewed since

Warning for Linux OS owners: FairWare virus is on its way

While the majority of ransomware threats aimed at Windows OS users, FairWare virus now sets its target on Linux OS users.

It seems to differ from its malwrae counterparts by a few features. Though the threat attempts to block servers and certain websites, it is still possible to remove FairWare. Some speculate that the threat takes the liking of corporate users since it causes more significant damage.

Likewise, there are bigger chances to receive the payment. In any case, we do not recommend making the transaction as there are no guarantees given. Instead, shift to FairWare removal. You can use to do that.

This threat is classified as ransomware, but the most intriguing feature is that it may not encrypt the files. Actually, it takes hold of the files and then transfers them to remote server. There have been cases with previous ransomware which simply deleted the personal data, but it is unlikely in this case. Nonetheless, FairWare malware demands 2 BTC which is even to 1,151.33 USD.

Taking a look at READ_ME.txt, the hackers seem to enjoy themselves since the manner of speech clearly bullies its victims. What is more, the average term given for retrieving the data is set to be two weeks.

The cyber criminals urge to contact fairware@sigaint.org only when the users have remitted the payment and had their server and payment ID codes. The message warns users not to ask supposedly foolish questions related to data recovery. Moreover, it does not offer to obtain any software which would verify the files being in the hackers' possession.

Analyzing this virus, it is likely that the current version is just an experiment. Linux OS users detected the virus after realizing that some of their websites were shut down. The file with the instructions is usually placed in the /root/ folder. It might be just the beginning of a bigger cyber campaign since the malware blocks websites and servers.

How does the virus infect computers?

Besides the removal, such question might indeed cause curiosity.

It is likely that FairWare ransomware mainly disperses via spam emails bearing malicious attachments. Unfortunately, hackers have reached a certain degree of mastery since differentiating a fraud from an official email became quite a challenge. Users have been attacked lately with fake emails from telecommunications, transportations, customs or tax institutions.

Such emails are forged in quite a persuasive way. After seeing the logo and credential of a supposed specialist, few users anticipate the danger of opening the malicious attachment. Furthermore, it is vital that you would increase the security of your operating system by installing a proper security application.

Later on, the ransomware might employ trojans or exploit kits as transmission tools. Thus, only an updated anti-spyware is able to detect on time before they sneak into the operating system. Lastly, stay alerted when visiting file-sharing domains. In general, cautiousness might reduce the chances of FairWare hijack.

The FairWare ransomware virus ransom note

The note is called READ_ME.txt.

We did not record the full text of the ransom note in our report.

How to remove FairWare ransomware virus

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 FairWare ransomware virus 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.

  1. Step 1: Disconnect the PC and unplug backup drives

    FairWare ransomware virus 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.

  2. Step 2: Save the ransom note and identify the family

    Find the ransom note, usually a .txt, .html or .hta file in every folder or on the desktop, and copy it with one or two encrypted files to a USB stick.

    From another device, upload them to ID Ransomware or No More Ransom's Crypto Sheriff, which name the family from the note and the file extension. Write down the contact address and your personal ID from the note for the report.

    Warning: Never contact the attackers from the infected Windows 11 or Windows 10 PC.

  3. Step 3: Check for a free decryptor

    For FairWare ransomware virus, 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.

  4. Step 4: Remove the ransomware before you restore or decrypt

    Restoring or decrypting files while FairWare ransomware virus 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.

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

  5. 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.

    Command Prompt running vssadmin list shadows
    Windows 11: vssadmin list shadows shows whether shadow copies exist.

  6. 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

  1. Click Start > Shutdown > Restart > OK.
  2. 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.
  3. Select Safe Mode with Networking from the list.Windows 7/XP

Windows 10 / Windows 8

  1. Right-click on Start button and select Settings.
    Settings
  2. Scroll down to pick Update & Security.

  8. Select Startup Settings.Startup settings
  9. Press Restart.
  10. Now press 5 or click 5) Enable Safe Mode with Networking.Enable safe mode

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:

  1. Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
  2. Click on More details.
    Open task manager
  3. Scroll down to Background processes section, and look for anything suspicious.
  4. Right-click and select Open file location.
    Open file location
  5. Go back to the process, right-click and pick End Task.
    End task
  6. Delete the contents of the malicious folder.

Step 3. Check program Startup

  1. Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
  2. Go to Startup tab.
  3. Right-click on the suspicious program and pick Disable.
    Startup

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:

  1. Type in Disk Cleanup in Windows search and press Enter.
    Disk cleanup
  2. 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).
  3. Scroll through the Files to delete list and select the following: Temporary Internet Files
    Downloads
    Recycle Bin
    Temporary files
  4. Pick Clean up system files.
    Delete temp files
  5. 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.

Effective elimination of the ransomware

At the moment, the only possible way to remove FairWare might be the automatic termination.

Meddling with the threat manually might not bring any wanted results. The security software is specifically created for confronting such viruses. The program will perform FairWare removal within a couple of minutes.

Later on, you need to consider where and how you will keep the files to avoid a similar unpleasant scenario in the future. FairWare virus might delete volume shadow copies, but you will evade the frustrating consequences if you keep the private data in several portable data storage locations.

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

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.

Protect the files you restore

Restore only after the scans are clean and the PC no longer shows ransom notes called READ_ME.txt in every folder; otherwise the restored copies can be damaged again.

Then build a backup that survives the next infection:

  • one copy in the cloud with version history
  • one on an external drive that is disconnected between backups
  • the working copy on the PC

Version history matters because a backup that syncs damaged files overwrites the good ones.

How to do this with the tools built into Windows: the 3-2-1 backup rule on Windows.

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 FairWare ransomware virus

When will a decryptor for FairWare ransomware virus be released?

Nobody can promise a date. When we last checked, on 7 October 2026, no free decryptor is known. Decryptors usually appear after one of three events:

  • police seize the attackers' servers and keys
  • the authors leak or publish the master keys
  • researchers find a mistake in how the ransomware generates keys

Some families got a tool within weeks, others never. Keep the encrypted files and the note on an external drive, check No More Ransom every few months, and follow news about the FairWare ransomware virus family. A decryptor may need an original file, so keep any unencrypted copies too.

How did FairWare ransomware virus get on my computer?

The way FairWare ransomware virus 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 ransom notes called READ_ME.txt in every folder, and check the Downloads folder and Installed apps sorted by date. Keep anything suspicious for your report, but do not run it again.

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.

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.

Did FairWare ransomware virus steal my files or passwords?

We do not know yet. Nothing published so far shows data theft by FairWare ransomware virus, but the only confirmed sign is ransom notes called READ_ME.txt in every folder, 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 FairWare ransomware virus 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.

What does READ_ME.txt tell me about the ransomware?

Quite a lot. The file name READ_ME.txt, 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.

Is READ_ME.txt from real ransomware or a bluff?

Look at your files rather than the note. If documents and photos have a new extension and will not open, the encryption is real. If files open normally, or only a few were renamed, the note may come from fake ransomware or extortion-only malware that claims more than it did.

Some wipers also leave notes like READ_ME.txt while destroying data with no way back. Identification services help here too: they recognise the note and tell you whether the family is known to encrypt, to bluff, or to wipe.

How do I open my .docx, .jpg and other files locked by FairWare?

You cannot open locked files normally while they stay encrypted, and renaming them will not help. Our earlier report did not record the extension that FairWare adds, so check one locked file name and the ransom note for it.

No free decryptor is known for this variant; check No More Ransom (nomoreransom.org) for updates. Do not rename the files, change the extension or edit them, because that can make recovery harder. Copy the locked files to an external drive before you clean the system, so a decryptor released later still has them.

Will Fortect remove FairWare ransomware virus?

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 FairWare ransomware virus, 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.
