How R3store ransomware virus behaves
From our report of Jun 2017 · not reviewed since
R3store threatens to damage the computer if victims don't pay the ransom
R3store is a new file-encrypting virus that aims at Windows operating system users.
Malware is based on Hidden Tear ransomware project and uses a strong encryption algorithm to damage files on targeted computer. During data encryption, it appends .r3store file extension to each of the affected file. It aims at various text files, pictures, media files, databases, etc. Generally, it targets the most popular and widely used files to cause bigger damage to the victims and encourage them to pay the ransom.
When users are prevented from opening their personal data, R3store ransomware drops READ_IT.txt file to each folder that includes encrypted files. What is more, it runs a pop-up window with a ransom-demanding message. Crooks ask to send $450 in Bitcoins to provided Bitcoin wallet address. Once users pay the ransom, they have to click the big button saying "I paid, Give me my files back!" and recover their files.
However, it may not happen. It's unknown if authors of the ransomware actually have working decryptor and are going to keep their word. Undoubtedly, cyber criminals are unreliable people. For this reason, it's better to remove R3store and protect a device from other problems.
On the affected computer, R3store also makes few changes on the system. One of its tasks is to make sure that it runs when users start his or her computer. Thus, ransomware always works in the background. It uses computer's resources and makes the system weaker.
Such cyber threats are often capable of installing other malicious programs and causing more problems. Once it strengthens its persistence, it starts scanning the system looking for the targeted files. When they are locked with strong cipher, R3store delivers a ransom-demanding window. Crooks try to scare people and encourage them to pay the ransom by telling that there's any other way to get back their files and computer.
The horrible message includes buttons that cover information about possible payment methods, the list of encrypted files and information how to buy Bitcoins. As we already mentioned, this does not guarantee that your files will be recovered. It protects your PC from other dangers and your money from being wasted for a useless cyber crime.

Ransomware uses tricky methods to infiltrate the device
Authors of R3store use numerous strategies to spread this file-encrypting virus.
These methods include infected email attachments, fake updates, bogus software downloads, and malvertising. Thus, users are tricked to click or install a malicious file. Malware executable might arrive as safely looking email attachment that pretends to be an invoice, statement or another important document. Ransomware executable might also be installed in the form of "crucial" software update.
Usually, such updates appear in pop-ups and other online ads. R3store hijack the system pretending to be a useful program that is distributed on various file-sharing sites and networks. Thus, in order to avoid crypto-malware, you need to browse the web carefully and think twice before clicking on various content.
The R3store ransomware virus ransom note
The note is called READ_IT.txt.
We did not record the full text of the ransom note in our report.
How to remove R3store 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 R3store 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.
Step 1: Disconnect the PC and unplug backup drives
Unplug the network cable or turn off Wi-Fi, and disconnect USB drives, external disks and network shares, so R3store ransomware virus cannot reach more files. Pause OneDrive, Google Drive or Dropbox sync, because synced folders upload the encrypted copies over the good ones.
Leave the PC on but offline while you read the next steps, since a restart can let the ransomware run again. This applies to Windows 11 and Windows 10 alike.

Step 2: Save the ransom note and confirm the family
Your files now end in
.r3storeand the instructions are inREAD_IT.txt. Save both to a USB stick, a copy of the note and two small encrypted files, before anything else.On another device, check them with ID Ransomware or Crypto Sheriff: the family name decides which decryptor, if any, can help. Keep the note's ID and contact line for your report.

Step 3: Check for a free decryptor
Our last check found that for R3store ransomware virus, no free decryptor is known (checked 7 October 2026). Look again yourself in the No More Ransom list and the free decryptor pages of Emsisoft, Avast and Kaspersky, which add new families every year.
A decryptor needs the ransomware gone first, or it encrypts the files again. Keep at least one copy of the encrypted files on an external drive, even if no tool works yet.

Step 4: Remove the ransomware before you restore or decrypt
Removing R3store ransomware virus does not bring the files back, but it has to come first. Start with Defender's Full scan, then the offline scan from the same Scan options page, which checks the disk before Windows loads.
If the scan cannot start, use Safe Mode with Networking. Delete the ransom notes only after you have saved a copy, because removal tools sometimes leave them behind on Windows 11 and 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
Windows keeps shadow copies for restore points and backups, and some ransomware fails to delete them.
vssadmin list shadowsin an administrator Command Prompt tells you at once whether any exist.If they do, right-click the folder that held your files, open Properties > Previous Versions, select a version from before the attack, and click Open to check it before you Restore or copy the files out. Windows 11 and Windows 10 both have the tab.

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
A backup made before the attack is the surest way back. Connect it only once the PC is clean, then restore from File History, Windows Backup, OneDrive's Restore your OneDrive or your own external copies.
Without a backup, try file recovery: the originals that R3store ransomware virus deleted may still be on the disk until something overwrites them. Install nothing new on the drive you want to recover from on the Windows 11 or Windows 10 PC.

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.
- 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.
- Now scroll down to find Advanced Startup section.
- 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.

Guidelines for R3store removal
File-encrypting viruses are complex programs that need proper treatment.
In order to remove R3store safely from the system, you have to employ a professional malware removal program, such as , or . It might be necessary if ransomware prevents from installing security tools.
After installing the program, we suggest scanning the system several times in order to make sure that all malicious components are deleted entirely from the system. After R3store removal, you can use data backups to recover your files. If you do not have them, please try our presented alternative recovery methods presented below.
[GI=method-1]R3store might prevent from installing security software necessary for malware removal. To solve this problem follow the steps below.
[GI=method-2]If you cannot run automatic ransomware removal, follow these steps and try again.
This professional tool might help to restore files encrypted by R3store ransomware. It is designed to recover deleted or corrupted files.
Windows Previous Versions feature might be useful in data recovery
If you need to restore only a few important files, you should take advantage of this Windows feature. It allows accessing previously saved versions of encrypted files. However, there's one condition. System Restore function has to be enabled on your PC before the R3store attack.
Recovr your files using ShadowExplorer
If Shadow Volume Copies are not deleted, this tool could help you to restore some of your files.
R3store Decryptor is not available yet.
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.
Protect the files you restore
Restore only after the scans are clean and the PC no longer shows files that end in .r3store and no longer open; 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.
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 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
- 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, can be your only hope to retrieve your invaluable files.
Questions about R3store ransomware virus
How do I open .r3store files?
You cannot open them by renaming or by choosing another program. The .r3store ending shows that R3store ransomware virus 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 R3store ransomware virus. Store the encrypted files on an external disk until then.
How did R3store ransomware virus get on my computer?
The way R3store 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 files that end in .r3store 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.
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.
Is there a free R3store ransomware virus decryptor?
We last checked on 7 October 2026, and for R3store ransomware virus 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 "R3store ransomware virus 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.
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.
Did R3store ransomware virus steal my files or passwords?
We do not know yet. Nothing published so far shows data theft by R3store ransomware virus, but the only confirmed sign is files that end in .r3store 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 R3store 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.
Can I just remove .r3store from the file names?
You can try it on a copy, but for real ransomware it will not help. The .r3store 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.
Can I delete READ_IT.txt?
Yes, the note itself is harmless text and deleting it does not affect your files. Keep at least one copy first, outside the infected PC. READ_IT.txt contains your personal ID and the attackers' contact details, which identification services use to tell which family encrypted your files, and which a decryptor may need later.
Police reports also ask for it. Once you have saved a copy, you can remove the notes from every folder after the ransomware program has been removed and your files are restored or backed up.
Will Fortect remove R3store 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 R3store 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.
