Iotr Virus – Why Is My Windows Infected?
The most frequent way to contract DJVU virus ransomware is by downloading and opening malicious attachments sent in emails or obfuscated files, downloaded from malicious websites. Other methods of getting infected include downloading software with malware embedded in it, accessing malicious websites, or by taking advantage of security flaws in the operating system or other software.
Iotr Virus – How Did I Get Infected?
It is advisable to be mindful when downloading and opening files from unknown sources, as the Iotr ransomware can be spread through malicious emails, websites, and downloads.
The following methods may be used to spread this virus:
- If it is sent to you as an e-mail attachment or a URL.
- By being downloaded from a shady site.
Iotr Virus – What Does It Do?
Once this variant of the ransomware infiltrates your computer, it will encrypt your data and require a ransom fee to obtain the decryption key. All encrypted files will have their file extensions changed to .iotr.
The primary intent of this ransomware is to leave its malicious payload files in certain Windows folders:
- %Local%
- %Temp%
- %Windows%
- %SystemDrive%
- %LocalLow%
- %AppData%
- %System%
- %system32%
The virus leaves a ransom note file named _readme.txt, which contains the following text:
The virus can insert several value entries into the Run and RunOnce Registries, which are key elements in the Windows operating system. These Registry entries will allow the virus to launch itself each time you boot your computer, meaning that it will keep running and causing damage to your machine.
What Are .iotr Files
Iotr ransomware is a malicious software that uses AES encryption algorithm to encode files, making them impossible to access without a decryption key. In order to obtain this key, victims of a DJVU ransomware infection may be asked to pay a ransom. During the infection process, the virus may run a scan, which can detect and encrypt various types of files. Iotr Virus may attack the following kinds of files for encryption:- Videos (.mp4, .avi, etc.).
- Audio (.mp3, .wav, etc.).
- Picture file kinds (.jpg, .png, .etc).
- Archive file formats (.zip, .rar, etc).
- Documents of different types (.docx, .pptx, etc.).
- Others.
After encryption, the files begin to appear like the following:
How to Open .iotr Files
The files encrypted by Iotr cannot be opened unless the user has a decryption key that corresponds to its cipher. The only way to obtain this key is to either pay the ransom demanded by the ransomware or have access to a decryptor.

What To Do If My Files Are .iotr?
If your files have been encryptedby Iotr ransomware’s cipher , it is important to keep in mind that there is no guarantee that the decryption key will work, and paying the ransom does not guarantee that you will get your files back. The only ways to get your files back are to have a backup, pay the ransom, or to check if researchers have developed a free decryptor.
How To Protect Windows from Iotr In The Future?
If you want to ensure your device is safe from malicious software in the future, we recommend you take the time to learn how to safely store your files to protect them from ransomware.
How to Remove Iotr Virus?
In order to get rid of the Iotr ransomware from your computer, it is highly recommended to use a trustworthy anti-malware program. The application will scan your system for the virus files associated with the ransomware. After the scan is completed, you should run a full system scan to guarantee that all malicious components are completely removed.
How to Decrypt / Fix .iotr Files?
The only way to decrypt files that have been encrypted by Iotr is to use the decryption key provided by the ransomware developers after paying the ransom. It is important to note that there is no guarantee that the key will work, and paying the ransom does not guarantee that your files will be returned. For this reason, we recommend attempting the STOP Ransomware decryption steps linked here before paying the ransom.

Step 2: Uninstall Iotr 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. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Step 3: Clean any registries, created by Iotr 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 Iotr there. This can happen by following the steps underneath:
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 Iotr
Step 5: Try to Restore Files Encrypted by Iotr.
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:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Iotr aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
