LQTOREQ Ransomware: .lqtoreq Files & Decryptor Guide

Share this post on social...

If you have discovered files ending in .lqtoreq, a file named README_LQTOREG.txt, or a recovery window displaying an apparently empty decryption-code field, your computer may have been affected by LQTOREQ ransomware.

LQTOREQ is a file-encrypting malware that has been reported to rename affected files by adding the .lqtoreq extension. Security researchers have also documented the README_LQTOREG.txt ransom note and a pop-up recovery window associated with the threat.

This guide explains what the .lqtoreq extension means, what the ransom note does, whether a free decryptor is available, and what you should do if your files have been affected.

What Is LQTOREQ Ransomware?

LQTOREQ is a type of ransomware designed to encrypt files and make them inaccessible. According to security research published in May 2026, affected files can receive the .lqtoreq extension.

For example:

photo.jpg may become photo.jpg.lqtoreq
document.docx may become document.docx.lqtoreq
video.mp4 may become video.mp4.lqtoreq

The appearance of this extension does not mean that simply renaming the file will restore it. The underlying file contents have been encrypted.

What Is README_LQTOREG.txt?

One of the reported indicators of LQTOREQ is a text file named:

README_LQTOREG.txt

The ransom note claims that files have been encrypted and directs the victim toward the attackers’ supposed recovery process. Research into the malware also documents a recovery pop-up asking for a decryption code.

If this file appears alongside numerous .lqtoreq files, treat it as a possible ransomware infection rather than an ordinary text document.

Why Is the Decrypt Box Empty?

The LQTOREQ recovery window documented by security researchers contains a field for a decryption code, but the displayed code area is empty.

The reported interface essentially asks the victim to enter a decryption code before selecting the decrypt option.

An empty field does not mean that there is a simple code you can guess. Avoid repeatedly entering random codes or downloading software advertised online as an unofficial “LQTOREQ decryptor.”

Is There a Free LQTOREQ Decryptor?

Current security research reports no free LQTOREQ decryptor.

However, ransomware recovery tools can change over time. Security researchers occasionally discover weaknesses that make decryption possible, so affected users should periodically check reputable resources rather than relying on random websites.

A good place to start is the official No More Ransom project, which maintains a collection of ransomware identification and decryption resources. The project notes that not every ransomware family currently has a solution and that new tools can become available later.

How to Identify the Ransomware Safely

If you are unsure whether the infection is actually LQTOREQ, consider using a reputable ransomware-identification service.

ID Ransomware allows users to submit a ransom note and/or an encrypted sample to help identify the ransomware family.

Visit ID Ransomware

Only upload files that you are comfortable sharing with the service, and avoid submitting confidential documents unnecessarily.

What to Do If You Have .lqtoreq Files

If your files have suddenly acquired the .lqtoreq extension, take a cautious approach.

1. Disconnect the affected computer

Disconnect the computer from Wi-Fi or unplug its network connection if practical. Isolating affected systems is a standard ransomware-response measure recommended by CISA.

2. Avoid deleting the encrypted files

Keep copies of the encrypted files if possible.

Even when no decryptor currently exists, preserving the affected files may be useful if researchers later develop a recovery method.

3. Preserve the ransom note

Keep README_LQTOREG.txt and other files created by the ransomware.

They can help identify the ransomware family and may be useful when seeking professional assistance.

4. Do not trust random decryptor websites

Be particularly careful with websites claiming to offer an instant or guaranteed LQTOREQ recovery tool.

A fake decryptor could introduce additional unwanted software or malware.

Instead, check established cybersecurity organizations such as:

No More Ransom

Kaspersky No Ransom

5. Check your backups

If you maintain an offline backup or a properly protected cloud backup created before the infection, it may provide the safest way to recover your files.

Do not immediately reconnect a backup drive to an infected computer. First make sure the affected system has been properly assessed and cleaned.

6. Consider professional assistance

If the encrypted files contain important business records, family photographs, financial documents or other irreplaceable information, consider consulting a reputable cybersecurity or digital-forensics professional.

Should You Pay the Ransom?

There is no guarantee that paying a ransom will result in successful file recovery.

The No More Ransom project advises against paying attackers because payment does not guarantee that victims will receive a working decryption solution.

CISA likewise recommends maintaining backups and advises against paying ransomware demands.

For this reason, it is generally better to investigate legitimate recovery options first.

Can Renaming .lqtoreq Files Fix Them?

No.

For example, changing:

picture.jpg.lqtoreq

to:

picture.jpg

does not normally reverse the encryption.

The extension is an indicator of what happened to the file; removing the extension does not restore the encrypted data.

Can System Restore Recover the Files?

System Restore should not be considered a ransomware decryption method.

It is primarily designed to restore certain Windows system settings and components. It should not be expected to reconstruct files that have been encrypted by ransomware.

Your best recovery possibilities may instead include a clean backup, a legitimate ransomware decryptor, or professional data-recovery assistance.

How Can You Protect Your Computer From Ransomware?

Good security practices can substantially reduce the risk of ransomware-related data loss.

Keep backups

Maintain regular backups of important documents and photographs. Where possible, keep at least one backup separated from the computer.

CISA recommends creating backups of critical systems and data as part of ransomware protection.

Keep software updated

Install security updates for Windows, browsers and other software.

Be careful with email attachments

Do not open unexpected attachments simply because they appear to come from a familiar company or contact.

Avoid pirated software

Unofficial software installers and cracked applications can be a source of malware infections.

Use reputable security software

Keep your security software active and updated, and investigate unexpected malware warnings rather than dismissing them.

Use multi-factor authentication

Where supported, enable multi-factor authentication on important online accounts. CISA includes MFA among its ransomware risk-reduction recommendations.

Frequently Asked Questions

Is LQTOREQ a virus?

LQTOREQ is described as ransomware, specifically file-encrypting malware. It can encrypt files and append the .lqtoreq extension.

What does .lqtoreq mean?

The .lqtoreq extension is associated with files encrypted by LQTOREQ ransomware. Simply removing the extension does not decrypt the file.

What is README_LQTOREG.txt?

It is a ransom-note file associated with LQTOREQ ransomware. Its appearance alongside .lqtoreq files can be an important indicator of infection.

Is there a LQTOREQ decryptor?

Current research reports that a free LQTOREQ decryptor is not available. Nevertheless, victims should continue checking reputable ransomware-recovery resources because legitimate decryptors can become available in the future.

Should I delete the .lqtoreq files?

Do not rush to delete them. Keeping copies may be useful for identification, professional analysis or future recovery efforts.

Can antivirus software decrypt my files?

Security software can help detect and remove the malware, but malware removal and file decryption are different processes. Removing the ransomware does not automatically restore already encrypted files.

Final Thoughts

LQTOREQ is a serious ransomware threat associated with the .lqtoreq file extension, README_LQTOREG.txt ransom note and a recovery window requesting a decryption code.

If you encounter these signs, avoid panic and do not rely on unverified websites promising guaranteed recovery. Disconnect the affected system where appropriate, preserve the encrypted files and ransom note, check clean backups, and use reputable ransomware-identification and decryption resources.
