Uyari is the name given to a new ransomware crypto-virus, which is believed to be targeting Turkish users as the ransom note is written in Turkish. That does not exclude the possibility of others being targeted and infected by the virus. Based on the latest HiddenTear project, in the ransom message the malware states it is CryptoLocker, much like the original CryptoWall ransomware. Uyari will encrypt files and add the .locked extension to them. Read the article through to see how you can remove the ransomware and possibly decrypt your files.

Uyari Ransomware – Distribution Method
Uyari ransomware might be using targeted attacks to infect users, mainly who speak Turkish, but other distribution methods are not an exclusion. It might also be distributed with various methods – it all depends what the cybercriminals decided to use as an entry point. Spam mail delivering letters with malicious attachments, exploit kits released for a software which still has a vulnerability or is not updated, social media and file-share networks – the possibilities are huge. Be very careful with what you do online and avoid suspicious emails, links, websites and the like. Do not give privileges to programs with an unknown origin.
Uyari Ransomware – A Closer Look
Uyari is the name of a ransomware, based on HiddenTear. It is named after the first word in the ransom note, which in English translates as “WARNING”. Believed to target Turkish users, because its ransom note is written in the Turkish language. This does not in any way exclude the possibility of other people to be targeted and infected by this crypto-virus. The ransom note also claims that the virus is CryptoLocker, much like the first CryptoWall ransomware did. The AVG malware researcher, Jakub Kroustek, has identified a sample as being part of HiddenTear after all.
Uyari ransomware creates the following files:
C:\Users\W7_MMD\.windowsServiceEngine
C:\Users\W7_MMD\Desktop\DOSYALARINIZA ULAŞMAK İÇİN AÇINIZ.html
and the following registry entry, afterward:
SOFTWARE\Microsoft\Windows\CurrentVersion\Run\WindowsServiceEngine
That tactic allows it to remain persistent and start with each boot of the Windows Operating System.
Next, the Uyari ransomware places the .locked file extension on encrypted files. After that operation is done, the file DOSYALARINIZA ULAŞMAK İÇİN AÇINIZ.html is loaded and it contains the ransom message, written in Turkish. You can see a picture of it here:
The text from the ransom note reads:

Step 2: Uninstall Uyari and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision.

The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Uyari on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Uyari there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Uyari
Step 5: Try to Restore Files Encrypted by Uyari.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
