IMI virus Removal Guide

What is IMI ransomware?

IMI ransomware is the cryptovirus that encrypts data and keeps files inaccessible until the ransom is paid

IMI ransomware virusIMI ransomware is the threat that demands money from victims whose data gets locked.

IMI ransomware – the virus that comes from a dangerous strain of crypto-extortion based malware. This Dharma ransomware version gets its name from the file appendix that appears at the end of each encoded file – .id-victims' ID.[].IMI. Once the system is infiltrated, and photos, documents, other types of data get the marker, the ransom is demanded from victims. As typical for this ransomware family, the program window appears on the screen that contains a general message about ransomware encryption and further actions. However, cybercriminals responsible for the malware distribution lists, paying the ransom as the only solution for you.

Sending Bitcoins or even contacting IMI ransomware virus developers via the email provided on ransom note FILES ENCRYPTED.txt and other files posted on the Desktop is not safe. This is the family of malware that Jakub Kroustek[1] is researching for a while already. He is the one that reports about new versions, like IMI and Bitx that came out one after the other. The price for your file recovery can go high as a few thousand dollars for the alleged decryption key, so stay away from even thinking about such a solution.

However, common files get all encrypted, in most cases. Ransomware is not running the encryption in system folders only
Ransom note FILES ENCRYPTED.txt – a file that contains contact details. The program window that gets opened is the one that provides the ransom-demanding message and instructions for Bitcoin purchasing. This window appears on the Desktop as Info.hta

Distribution Ransomware is mainly delivered via spam emails that contain malicious script-filled files[2] or direct payload droppers as attachments or hyperlinks
Elimination You should remove IMI ransomware as soon as you can and rely on anti-malware tools that can detect malicious-behavior and delete dangerous programs from the machine fully
Repair Since files in various places get affected by the threat, you need an additional system scan with FortectIntego or a similar PC tool. Software like this can find and possibly restore damaged data in system folders

IMI ransomware is the typical version of Dharma/ CrySis virus because particular features like ransom demanding message, program window with general instructions, and the appendix pattern involving ID, contact email are the same. The family is known for changing little things about each version and releasing threats into the wild at least once a month for almost four years now.

The encryption is a process that starts immediately after the initial IMI files virus infiltration and begins with checking the system for particular types of files that can be encoded. Photos, videos, audio files, and documents get changed and locked from the access, so ransomware creators have a reason for blackmail.

Once data gets encrypted, the ransom note appears on the screen. The program window is showing brief payment and cryptocurrency purchasing instructions, but the text file FILES ENCRYPTED.txt displays unique contact. The message from IMI ransomware creators reads the following:

all your data has been locked us
You want to return?
write email or

Even though the official decryption tool for the threat is not developed yet, you can store virus-related files and hope that such software is going to be released soon. Paying cannot give you any positive results,[3] so remove IMI ransomware instead and restore encrypted files using other methods.

You should ignore any messages from these criminals and all the claims that paying is the only option to get your files back. IMI ransomware removal is a process that requires attention and professional anti-malware tools because threats like ransomware inject various files in different system places to ensure the persistence and damage the PC permanently. IMI cryptovirusIMI ransomware - a virus that infiltrates the system silently and appears on the screen with the ransom demand when data gets permanently locked. There is nothing harmless about threats like IMI ransomware that focus on getting peoples' money by damaging their belongings. These malicious people don't care for your files and value of the data, devices, so there is no reason to contact them and hoping for mercy. If you don't want to pay the ransom, you shouldn't write or try to reach malicious actors.

When people write emails to criminals, they can send victims more malicious files and direct malware designed to steal information from the machine or damage the computer once and for all. When you encounter IMI ransomware and receive the ransom note, you should take immediate action and try to eliminate the threat as soon as possible.

Experts[4] always talk about risks and danger behind the content that IMI ransomware can load in system folders and other places like Windows Registry. To fix such damage, you can run FortectIntego or a similar PC repair tool and check for anything possible affected or corrupted.

The more time you give for these people that managed to infect your machine, the more corrupted your device gets, and the more help it needs. When IMI ransomware is done with encryption, it goes through system functions, disables security features and applications, so you cannot easily remove the threat nor recover affected files.

Since IMI ransomware virus disables security functions, installs other malicious programs and changes system settings behind your back, you should run the machine in Safe Mode with Networking and then employ an anti-malware tool that can detect malicious behavior-based programs and files, clean the machine from malware. IMI ransomware Dharma IMI ransomware - the file-locking malware that shows a program window named the same as contact email.

Cryptovirus infiltration methods and possible ways to avoid such infection

Cyber intruders all use deceptive techniques that help to trick people into installing the malicious script. Unfortunately, the more dangerous threats use silent methods that allow them to get on the machine and affect the system silently. Blackmail-based malware like this mainly relies on spam email campaigns that use names of common and popular companies, services to hide their own products, and malicious purposes of email notifications.

When the email is received and opened, it shows either a hyperlink and deceptive message or includes the common type of file attached. In most cases, such documents have malicious macros embedded on the file or hyperlinks trigger the download of a payload dropper automatically.

The best way to rely on is being suspicious. Anything that raises questions should be considered potentially dangerous and inspected further. Look out for grammar mistakes or typos on such emails or simply delete any message that you didn't expect to get. Clean the email box more often to avoid anything dangerous landing on the system.

Ensure that IMI ransomware virus is terminated before any files recovery

You need to note that the IMI ransomware virus is the malicious program capable of damaging the machine significantly and quickly. This is a powerful virus that can achieve anything in a short time, even though the virus tends to delete itself from the system after the encryption.

IMI ransomware removal is crucial for the state of the device even though the core files are no longer in the machine. Any data associated with this intruder can trigger additional encryption processes or damage functions, third-party applications. Eliminate the ransomware as soon as you notice encrypted files.

When the victim reacts as soon as possible, it is easier to remove IMI ransomware because not much gets changed besides those encrypted files. You can download SpyHunter 5Combo Cleaner or Malwarebytes and run the full scan on the machine to terminate malicious processes completely. Then files can get recovered on the safe and malware-free computer.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from IMI and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
