Iowd Virus – Why Is My Windows Infected?
It is important to take precautions when downloading and opening files from unknown sources, as DJVU ransomware is typically spread through obfuscated files, malicious emails, websites, and downloads.
Iowd Virus – How Did I Get Infected?
It is a good idea to be wary when downloading and opening files from unfamiliar sources since DJVU ransomware can generally be disseminated via malicious emails, webpages, and downloads, like:
- If it is sent to you as an e-mail attachment or a URL.
- By being downloaded from a shady site.
Iowd Virus – What Does It Do?
Once the DJVU ransomware is installed on your computer, it will encrypt any data stored on the device and require a ransom payment for the decryption key. As well as this, the file extensions of all encrypted files will be changed to .iowd. The primary aim of this ransomware is to firstly deploy its payload files in certain Windows directories:
- %Local%
- %Temp%
- %Windows%
- %SystemDrive%
- %LocalLow%
- %AppData%
- %System%
- %system32%
The virus leaves a ransom note file, named _readme.txt, as one of its actions. The content of the file is as follows:
The virus may modify the Run and RunOnce Registries to contain various value entries. These Registry
entries are designed to automatically launch certain virus files when Windows first starts up.
What Are .iowd Files
Iowd ransomware has encrypted files using the AES encryption algorithm making them inaccessible without a decryption key, which can only be obtained by paying a ransom. The virus may have run a scan, resulting in the detection and encryption of various types of files. These files can only be unlocked with the decryption key.The malware may scan for and encrypt files of the following kinds:
- 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 being encrypted, the files start to appear like the following screenshot shows:

How to Open .iowd Files
The encrypted files belonging to Iowd cannot be accessed without a decryption key that matches its cipher. The only way to get the key is to either pay the ransom money asked by the ransomware or find a decryptor.
What To Do If My Files Are .iowd?
If your data is encrypted by Iowd ransomware, the only ways to restore them are to have a backup, pay the ransom, or to look for a free decryptor for the cipher that might have been developed by researchers. However, it is important to note that there is no guarantee that the decryption key will work, and paying the ransom does not necessarily guarantee the restoration of your files.
How To Protect Windows from Iowd In The Future?
If you’re looking for ways to secure your device in the future, we recommend that you learn how to safely store your important files. By taking the necessary measures to protect your files from ransomware, you can ensure that your device is always secure. One way to do this is to learn how to safely store your files to protect them from ransomware.
How to Remove Iowd Virus?
If your computer has been infected with Iowd ransomware, the best way to remove it is to use a reliable anti-malware program. This program will detect and delete any virus files associated with this ransomware. To ensure that all malicious components of the virus have been completely removed, it is important to run a full system scan. Doing so will help keep your computer safe and secure.
How to Decrypt / Fix .iowd Files?
The only way to decrypt files that have been encrypted by the Iowd ransomware is to obtain and use the decryption key provided by the developers, although there is no guarantee that this will work. Paying the ransom does not guarantee that your files will be returned, which is why we recommend first trying out the STOP Ransomware decryption steps linked here before paying the ransom.

Step 2: Uninstall Iowd 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 Iowd 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 Iowd 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 Iowd
Step 5: Try to Restore Files Encrypted by Iowd.
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 Iowd 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.
