How To Remove TYCX Ransomware [Virus Removal Guide]

If you cannot open your images, documents, or files and they have a .tycx extension, then your computer is infected with the STOP/DJVU ransomware.
This ransomware encrypts the personal documents found on the victim’s computer with the “.tycx” extension, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victim’s desktop in the “_readme.txt” file.

What is the TYCX ransomware?

TYCX is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.tycx” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin cryptocurrency, in exchange for access to data.

When you are first infected with the TYCX ransomware it will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.tycx”, so that you are no longer able to open them.

Once the TYCX ransomware has encrypted the files on your computer, it will display the “_readme.txt” file that contains the ransom note and instructions on how to contact the authors of this ransomware. The victims of this ransomware will be asked to contact these malware developers via the support@fishmail.top and datarestorehelp@airmail.cc email addresses.

This is the ransom note that the TYCX ransomware will show to its victims:

Here is a summary of the TYCX ransomware:

Ransomware family: STOP/DJVU ransomware
Extensions: .tycx
Ransomware note: _readme.txt
Ransom: From $490 to $980 (in Bitcoins)
Contact: support@fishmail.top and datarestorehelp@airmail.cc emails
Symptoms: The images, videos, and other documents have the “.tycx” extension and cannot be opened by any programs
File recovery: Unfortunately, it is not currently possible to decrypt the files encrypted by the TYCX ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can decrypt them in the future.

How did the TYCX ransomware get on my computer?

The TYCX ransomware is distributed via spam email containing infected attachments, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs.

Here’s how the TYCX ransomware might get on your computer:

Spam emails: Cybercriminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the TYCX ransomware.
Be alert for people trying to trick you. Whether it’s your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it’s easy to spoof phone numbers, so a familiar name or number doesn’t make messages more trustworthy.
Cracks and keygens: The TYCX ransomware is distributed using fake software cracks or through free programs you download off of the Internet.
Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.
Exploits: The TYCX ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.
Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

Remove the TYCX ransomware and recover the files

It’s important to understand that by starting the removal process you risk losing your files, as we cannot guarantee that you will be able to recover them. Your files may be permanently compromised when trying to remove this infection or trying to recover the encrypted documents.
We cannot be held responsible for losing your files or documents during this removal process.

It’s recommended to create a backup image of the encrypted drives or files before proceeding with the malware removal instructions so that you can restore them if the decryption keys are recovered from the cybercriminals’ servers. To create a backup for your encrypted files or drives, you can use EaseUS Todo Backup Free.

This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free.
Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.

To remove the TYCX ransomware, follow these steps:

STEP 1: Start your computer in Safe Mode with Networking
STEP 2: Use Malwarebytes to remove TYCX ransomware
STEP 3: Use HitmanPro to scan for Trojans and other malware
STEP 4: Double-check for malware infections with ESET Online Scanner
STEP 5: Restore the files encrypted by the TYCX ransomware

STEP 1: Start your computer in Safe Mode with Networking

In this first step, we will start your computer in Safe Mode with Networking to prevent TYCX malicious drivers and services from loading at Windows start-up. We’re using Safe mode because it starts Windows in a basic state, using a limited set of files and drivers.

Windows 11Windows 10Windows 7

Safe Mode with Networking starts Windows with only the essential drivers and services, which stops most malware from loading — making it much easier to remove. First, we’ll open the Windows Recovery Environment (winRE):

Press Windows key + I to open Settings. If that doesn’t work, right-click the Start button and select Settings. Then, in the right-hand pane, click Recovery.
Under Advanced startup, click Restart now. Save any open work first — your PC will restart immediately.

Your PC will restart into the Windows Recovery Environment. From there, follow these steps to reach Safe Mode:

On the Choose an option screen, select Troubleshoot.
On the Troubleshoot screen, click Advanced Options.
On the Advanced Options page, click Startup Settings.
On the Startup Settings page, click Restart.
After your PC restarts, you’ll see a list of startup options. Press 5 or F5 to start Safe Mode with Networking.
You’ll know you’re in Safe Mode when “Safe Mode” appears in the corners of the screen. Now continue with the next step of this guide — downloading and running Malwarebytes (explained in Step 2).

Press Windows key + I to open Settings. If that doesn’t work, click the Start button and select Settings (the gear icon).
In the Windows Settings window, select Update & Security, then click Recovery.
Under Advanced startup, click Restart now. Save any open work first — your PC will restart immediately.

Your PC will restart into the Windows Recovery Environment. From there, follow these steps to reach Safe Mode:

On the Choose an option screen, select Troubleshoot.
On the Troubleshoot screen, click Advanced Options.
On the Advanced Options page, click Startup Settings. (On Windows 8, this option is labeled Windows Startup Settings.)
On the Startup Settings page, click Restart.
After your PC restarts, you’ll see a list of startup options. Press 5 or F5 to start Safe Mode with Networking.
You’ll know you’re in Safe Mode when “Safe Mode” appears in the corners of the screen. Now continue with the next step of this guide — downloading and running Malwarebytes (explained in Step 2).

Safe Mode with Networking starts Windows with only the essential drivers and services, which stops most malware from loading — making it much easier to remove. Here’s how to get there on Windows 7:

Remove any CDs, DVDs, or USB drives from your computer, then restart it.
As soon as the computer starts (when the hardware information appears on screen), press the F8 key repeatedly until the Advanced Boot Options menu appears. If Windows starts normally instead, you pressed F8 too late — restart and try again.
On the Advanced Boot Options screen, use the arrow keys to highlight Safe Mode with Networking, then press Enter.
Once you’re in Safe Mode with Networking, continue with the next step of this guide — downloading and running Malwarebytes (explained in Step 2).
Can’t get into Safe Mode with Networking? No problem — you can run the Malwarebytes scan in normal mode instead and continue the guide from there.

STEP 2: Use Malwarebytes to remove TYCX ransomware

While the computer is in Safe Mode with Networking, we will download, install and run a system scan with Malwarebytes.

Malwarebytes is one of the most popular and trusted anti-malware tools for Windows — and it’s completely free for removing infections. It catches threats that many antivirus programs miss, including adware, browser hijackers, and trojans. Follow the steps below to scan and clean your PC in just a few minutes.

Download Malwarebytes

Click the button below to download the latest version of Malwarebytes for Windows from the official source. The free version is all you need — it will scan your computer and remove adware, browser hijackers, and other malicious software at no cost.

Malwarebytes Free for WindowsScans and removes malware at no cost
Download MalwarebytesOfficial installer for Windows 11 and 10. Your download starts right away.Want real-time protection? See Malwarebytes Premium
Install Malwarebytes

When the download finishes, open your Downloads folder and double-click the MBSetup file. If Windows shows a User Account Control pop-up, click “Yes” to allow the installation.
Follow the On-Screen Prompts to Install Malwarebytes

The setup wizard will walk you through a few quick screens:
- Choose where you’re installing the program — “Personal Computer” or “Work Computer” — then click Next.
- Malwarebytes will now install on your device. This usually takes under a minute.
- When installation is complete, the “Welcome to Malwarebytes” screen will open automatically.
- On the final screen, click Open Malwarebytes to launch the program.
Enable “Scan for Rootkits”

Before scanning, turn on rootkit detection so Malwarebytes can find even the most hidden threats. Click the Settings gear icon on the left side of the screen.

In the settings menu, find “Scan for rootkits” and click the toggle so it turns blue.

Done? Click “Dashboard” in the left pane to return to the main screen.
Start the Scan

Click the blue Scan button. Malwarebytes will automatically update its virus database and start checking your computer for malware.
Wait for the Scan to Finish

The scan checks your entire system for browser hijackers and other malicious programs, so it can take 5 to 20 minutes depending on your computer. Feel free to do something else — just check back occasionally to see the progress.
Quarantine the Detected Threats

When the scan is done, you’ll see a list of everything Malwarebytes found — malware, adware, and potentially unwanted programs. Click the “Quarantine” button to remove all of them at once.

Malwarebytes will now remove the malicious files and registry entries and move them safely into quarantine.
Restart Your Computer

Some threats can only be fully removed after a reboot. If Malwarebytes asks you to restart, click Yes. Once you’re logged back in, Malwarebytes has finished removing the threats it found.

When the malware removal process is complete, your computer should start in normal mode (if not, simply restart your device to exit Safe Mode) and continue with the rest of the instructions. We do recommend that you run another scan with Malwarebytes once you’re in Normal mode to make sure all the malicious files were removed.

STEP 3: Use HitmanPro to scan for Trojans and other malware

In this third step, while the computer is in normal back, we will download and run a scan with HitmanPro to remove the TYCX ransomware and other malicious programs.

HitmanPro is a second-opinion scanner — it’s designed to catch what your main antivirus might have missed. Instead of relying on a single detection engine, it checks the behavior of files in the locations where malware usually hides. Anything suspicious gets sent to the cloud, where it’s analyzed by two of the best antivirus engines available: Bitdefender and Kaspersky.

Good news: scanning is completely free, with no limits. You only need a license when it’s time to remove what was found — and even then, you can activate a free one-time 30-day trial to clean your PC at no cost. (A full license is $24.95 per year for 1 PC.)

Download HitmanPro

Click the button below to download HitmanPro. Remember — the scan is free, so you have nothing to lose by checking your PC.

Install HitmanPro

When the download finishes, open your Downloads folder and double-click the file: “hitmanpro.exe” on 32-bit Windows, or “hitmanpro_x64.exe” on 64-bit Windows.

If a User Account Control pop-up asks whether HitmanPro can make changes to your device, click “Yes” to continue.
Follow the On-Screen Prompts

On the HitmanPro start screen, click “Next” to begin the system scan. No lengthy setup required — it goes straight to work.
Wait for the Scan to Finish

HitmanPro will now check your computer for malicious programs. This usually takes just a few minutes thanks to its cloud-based scanning.
Review the Results and Click “Next”

When the scan is done, HitmanPro will show you everything it found. Click “Next” to remove the detected threats.
Click “Activate Free License”

To remove the malicious files, click the “Activate free license” button. This starts your free 30-day trial — no payment details needed — and unlocks the full cleanup.

When the removal is complete, HitmanPro will show a summary of everything it cleaned. Click Next, then click Reboot if prompted. If there’s no reboot prompt, just click Close — your PC is clean.

STEP 4: Double-check for malicious programs with ESET Online Scanner

In this fourth step, we run a scan with ESET Online Scanner to remove any leftover files from the TYCX ransomware and other malicious programs.

ESET Online Scanner is a free second-opinion scanner that performs a deep, full-system check for viruses, trojans, rootkits, and other malware. We use it as the final step because it’s thorough — if anything slipped past the previous scans, ESET will find it. A clean result here means your computer is malware-free.

Download ESET Online Scanner

Click the button below to download ESET Online Scanner.

ESET Online ScannerFree one-time malware scan from ESET
Download ESET Online ScannerOpens the official download page in a new tab.
Run the Installer

When the download finishes, open your Downloads folder and double-click “esetonlinescanner.exe“.
Install ESET Online Scanner

On the start screen, select your language from the drop-down menu and click Get started.

On the Terms of use screen, click Accept.

Choose your preferences for the Customer Experience Improvement Program and the Detection feedback system (either choice is fine), then click Continue.
Start a Full Scan

Click Full Scan — this checks your entire computer, not just the common hiding spots.

Select Enable for Detection of Potentially Unwanted Applications — this lets ESET catch adware and bundled junk programs, not just viruses. Then click Start scan.
Wait for the Scan to Finish

ESET will now check every file on your computer. Because it’s a full scan, this can take a while — often an hour or more, depending on how much data you have. Leave it running in the background and check on it from time to time.
Review the Results

When the scan completes, the Found and resolved detections screen appears. Any threats found were automatically cleaned and quarantined — there’s nothing extra you need to do. Click View detailed results if you want to see exactly what was removed.

If ESET found nothing — congratulations, your computer has passed the final check and is malware-free.

STEP 5: Restore the files encrypted by the TYCX ransomware

Unfortunately, in most cases, it’s not possible to recover the files encrypted by this ransomware because the private key which is needed to unlock the encrypted files is only available through the attackers. However, below we’ve listed three options you can use to try and recover your files.

Make sure you remove the malware from your computer first, otherwise, it will repeatedly lock your system or encrypt files. If you suspect that your computer is still infected with malware, you can run a free scan with Emsisoft Emergency Kit.

Option 1: Use Emsisoft Decryptor for STOP Djvu to restore the files

If your files were encrypted with an offline key there is a chance you can recover them by using Emsisoft Decryptor for STOP Djvu decryption tool. Follow the below guide to recover your files using the Emsisoft Decryptor for STOP Djvu.

10 Rules to Avoid Online Scams

Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.

Stop and verify before you click, log in, download, or pay.

Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).

If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.

Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.

If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.

Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.

If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.

Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.

If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.

Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.

If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.

Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.

If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.

Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.

If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).

Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.

If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.

Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.

If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.

Move quickly. Speed matters for disputes, account recovery, and limiting damage.
- Stop payments and contact: do not send more money or respond to the scammer.
- Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
- Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
- Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
- Scan your device: remove suspicious apps or extensions, then run a full malware scan.
- Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
- Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.

These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
