How yyy0 ransomware behaves
From our report of Sep 2018 · not reviewed since
yy0 ransomware — a crypto-virus that marks encrypted files with .davilarita@mail.com.yyy0 file extension
yyy0 ransomware is a file-locking virus which makes your data useless after the encryption process.
There is no information on what particular encryption method is employed by this cyber threat, but each encrypted file is marked with .davilarita@mail.com.yyy0 file extension. This appendix makes it easier to determine modified files from untouched ones. After your photos, videos, music or documents are locked, the ransom note is generated and placed in every existing folder.
This file is called help.txt and contains only a few sentences about the ransomware attack. Cybercriminals behind this virus are offering to test their decryption service and recover 1-2 files (less than 3MB) by writing them via the provided email address davilarita@gmail.com.
However, we advise you to not think about contacting these people in any way. Keep in mind that you are dealing with hackers who can easily take your ransom and then leave you with nothing.
yyy0 ransomware virus modifies various data to extort money from victims. It is done by employing sophisticated encryption methods and changing the target files in general. After this process is done, virus marks those files with a .davilarita@mail.com.yyy0 file extension.
The whole process makes your data useless, and the only way to recover files is the alleged decryption tool or the backup. However, you should connect your external hard drive or similar devices only after virus removal. Otherwise, it can repeat its encryption.
Also, when the encryption process is performed, ransomware creates a ransom note which is used to inform the victim about files' loss. The virus places a copy of the ransom note in each existing folder on the system. This file called help.txt contains contact email address and instructions on how to reach the people behind the virus.
The ransom note reads the following:
As we have mentioned before, paying the ransom is not a good idea as this may lead you to the permanent data and money loss. You should remove yyy0 ransomware as soon as possible and then start thinking about recovering the locked data. Remember, if kept for too long, this intruder can be used to unlock your system's backdoors or download other malware to the system.
Files related to this ransomware can be detected as malicious by your antivirus, so, if you found any of these on the system, be aware that you are infected with the cryptovirus: TR/Crypmodadv.tuglz; Win32:Malware-gen; Trojan.Agent (A) and more. Because of this reason, the best solution for yyy0 ransomware removal is anti-malware tools like because it can detect various ransomware-related files and also fix its damage.
We have also provided several ways that you can use to block the virus before a scan. They can be found below the article. Once you disable the malware, use automatic virus removal by running a full system scan to detect all infected files on your computer.

Take precautionary measures to avoid ransomware infections
Most likely, ransomware-type viruses spread through spam messages which crooks spread around by using exploit kits and similar technologies.
Dangerous payload comes in the form of an attachment or link inserted into the message. Be careful with phishing emails as they might be sent for wrong purposes. Better delete all dubious spam messages that you receive to avoid possible dangers.
Furthermore, it is advisable to stay away from third-party networks such as Peer-to-Peer ones. Sites such as Torrents or eMule come provided by secondary sources and often lack essential protection.
Due to that, various infections can easily inject harmful components into those web pages in the form of a link. To add, install robust antivirus software to protect your computer system automatically from various infections that might occur in your way while you are browsing the web.

How to remove yyy0 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 yyy0 ransomware 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
Yyy0 ransomware 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
help.txtand one or two files ending in.davilaritato 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 yyy0 ransomware, no free decryptor is known (checked 6 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.

Step 4: Remove the ransomware before you restore or decrypt
Restoring or decrypting files while yyy0 ransomware 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.

Eliminate yyy0 ransomware with anti-malware
If you are thinking about the yyy0 ransomware removal, we have a solution for you.
All you need to do is download and install expert-tested anti-malware that was approved to detect this virus and eliminate its damage, such as fix changed files or registry entries. However, you can feel free to pick any of your own wanted computer security software.
Experts from NoVirus.uk claim that manual removal is genuinely not advisable for this type of cyber threat. Why so? Ransomware-type viruses are dangerous infections themselves. Nevertheless, they leave various harmful components behind them which might be hard to detect for a regular user.
Moreover, after you remove yyy0 ransomware from your PC, you should consider recovering your data and also performing system backups for the future cases. This is highly advisable to make sure that virus-related content is no longer active in your computer system.
[GI=method-1]Enable the Safe Mode with Networking function on your computer. Follow these steps to achieve such goal:
[GI=method-2]You need to activate the System Restore function by following this guide. This needs to be done to disable the ransomware-type virus:
Use this tool to recover files which were corrupted by yyy0 ransomware and followed each step cautiously during the entire process.
Windows Previous Versions feature might help with data recovery:
This method might be useful if you had activated the System Restore feature before the cyber attack had launched.
Use Shadow Explorer to recover data:
This tool might be helpful and let you get some corrupted files back. However, if the virus has damaged Shadow Volume Copies of locked documents, there is a big chance that this method will be useless.
There is no official yyy0 ransomware decryptor.
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.
Make the next attack harmless
Yyy0 ransomware could only hurt the files that had no second copy, and the signs (files that end in .davilarita and no longer open) showed exactly which ones those were.
The 3-2-1 rule fixes that:
- three copies
- two media
- one disconnected
A practical version for a home PC: OneDrive or another cloud backup with version history, plus an external disk that you plug in once a week for File History and then unplug. Test a restore now and then by opening a few files from the backup on another device.
Details, schedules and what not to back up are in our 3-2-1 backup guide for Windows.
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity.
While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important - recover your lost files
Ransomware is one of the biggest threats to personal data.
Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as can also be effective and restore at least some of your lost data.
Questions about yyy0 ransomware
Should I pay the ransom in help.txt?
Not before you have tried everything else. Identify the family from help.txt and one encrypted file, check No More Ransom for a free decryptor, and look for clean copies in OneDrive, backups and Previous Versions.
Paying funds further attacks, may be illegal if the group is sanctioned, and is no promise of a working key: many victims get partial or broken decryption. If you consider paying for business-critical data, involve the police and a professional incident responder first, and never pay through intermediaries who promise their own decryption.
How do I open .davilarita files?
You cannot open them by renaming or by choosing another program. The .davilarita ending shows that yyy0 ransomware 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 yyy0 ransomware. Store the encrypted files on an external disk until then.
Is there a free yyy0 ransomware decryptor?
We last checked on 6 October 2026, and for yyy0 ransomware 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 "yyy0 ransomware 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.
How did yyy0 ransomware get on my computer?
The way yyy0 ransomware 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 .davilarita 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 yyy0 ransomware steal my files or passwords?
We do not know yet. Nothing published so far shows data theft by yyy0 ransomware, but the only confirmed sign is files that end in .davilarita 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 yyy0 ransomware 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 .davilarita from the file names?
You can try it on a copy, but for real ransomware it will not help. The .davilarita 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 help.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. help.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 yyy0 ransomware?
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 yyy0 ransomware, 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.
