Do you see inaccessible .iiss files on your PC? If yes, we are sorry for this issue. Your computer and data have been compromised by ransomware. Keep reading to find out more details about the nasty Iiss virus as well as how to get rid of it.
What is Iiss Virus?
Iiss is called to a ransomware infection that causes damage to computer operating systems and personal data. The malicious software has been released in active campaigns against users worldwide. The virus has been reported by security researchers to be a strain of the infamous STOP ransomware. It appears to be yet another variant that aims to encode files that are likely to store valuable personal information. Its name comes from the malicious extension .iiss that the virus appends to every file it locks.
How to Recognize Iiss Ransomware Virus?
Iiss ransomware virus becomes visible to its victims after the end of the attack. At first, it tricks people into running it on their machines. Then it performs a long sequence of malicious activities that cause damage to both the computer operating system and data stored on it. The ransomware corrupts the settings of essential system components like those of the Registry Editor. During the attack, it activates a special module to encode target files with the strong AES cipher. The most vivid trait of this ransomware infection is the extension .iiss that appears appended to the name of all encrypted files. If you see a file renamed with this extension it means that you cannot open or use the file until a special decryption tool restores its code.
How to Remove .iiss File Extension?
The .iiss file extension indicates that the file that contains it in its name is locked by the new STOP/Djvu ransomware. Unfortunately, files that store important personal information are likely to be encrypted. This includes documents, banking details, audio and video files, images, photos, and even archives. The sad news is that the removal of the .iiss extension won’t recover files. They need to be decrypted by a reliable decryption tool. One way to get such a tool is to act as requested by hackers. Their demands can be found in a ransom note file called _readme.txt. The information in this file reveals that hackers expect victims to contact them at a given email address. Another detail that becomes clear is that they require a ransom payment of $490 – $980 in cryptocurrency.

Must Read Iiss Ransomware Information
This piece of malicious code is based on the code of a well-known ransomware called STOP/Djvu. In case of infection with this virus, it is obligatory to remove malicious files before using the PC again. Beware that reinstalling your computer system is not a step that guarantees the complete removal of the threat. In addition, it won’t recover locked data.
Iiss virus is being spread via different methods. The most probable one is malspam. Malspam is called to malicious spam email messages that contain suspicious links and file attachments. They are often disguised as reliable sources sent by prominent organizations. As soon as the user opens the file or click the link, Iiss ransomware initiates the attack and starts to drop malicious files on the computer.
The ransomware payload could be started by a website that is infected with the code or a free download/torrent file as well. Cheats for games, hacks, and cracks, fake software could also have malware inside.
Once executed on the system, the ransomware is capable of evading detection and reaching the data encryption stage. During this stage, it encrypts your data by modifying its code. Since code modifications are realized with the help of the AES cipher algorithm, .iiss files appear as if they are broken soon after the virus encrypts them.
Afterward, the ransomware places a ransom message inside folders with encrypted data. This note is named _readme.txt. It has instructions that urge victims to send money to threat creators. It claims that upon payment confirmation your data will get restored. However, no guarantee for this. You cannot be sure that you will get your files after paying.
The virus will present you with the following text message:
ATTENTION!
Don’t worry, you can return all your files!
All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.
This software will decrypt all your encrypted files.

We beg you to discard all nasty statements. They aim to provoke you and make you act as requested. Yes, it is true that the newest STOP ransomware strains are hard to decrypt by security experts due to some changes in the code. But don’t forget that they keep investigating the code of this ransomware in order to find flaws that will enable them to create a free decryption tool.
So back up your .iiss files and wait until they come up with a solution. We at Sensorstechforum.com have never considered a ransom payment as an effective solution. An amount of $490 – $980 will only stimulate hackers to continue spreading malicious software that harasses online users. If you want to try to restore your files, you could check the alternative solutions provided in our guide. Beware that none of them provides a 100% guarantee.
First, you should remove Iiss virus along with all associated malicious files and objects. Otherwise, the ransomware will repeatedly encrypt files on the compromised computer.

Step 2: Uninstall Iiss 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:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Iiss 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 Iiss 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 Iiss
Step 5: Try to Restore Files Encrypted by Iiss.
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 Iiss 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.
