Coom virus Removal Guide
What is Coom ransomware?
Coom ransomware is the threat that sets the ransom note as lock screens and desktop when the ransom note text file is red
Coom ransomware is the program that locks files on the machine and immediately after that delivers money demanding messages on the desktop directly or in the text file placed in multiple folders. Coom ransomware is the cryptovirus that gets released on the system to encrypt common files and make them useless. Developers designed the threat to then release a ransom note READ_IT.txt that directly states what the victim should do next – pay at least 0.015BTC., the ransom can differ from victim to victim, depending on the target and the value of stored and affected files. The particular file is not displaying much information, only stating that the person needs to pay to get those files unlocked and how to obtain Bitcoins for the payment. There is no contact information that could help to communicate with virus developers, so victims have not many options.
However, paying Coom ransomware virus creators shouldn't be considered a solution no matter what because cybercriminals are not worthy of your trust. By paying the ransom, you risk getting your money collected without receiving a decryption tool of any sort. This is the threat that encrypts files in multiple formats and uses the AES encryption algorithm for that. Also, this is the version of old Eda2 ransomware, so there is no reason to think that coding has some flaws. Cybercriminals may have perfected the coding and made sure to ensure that this threat is not easily detected and removed.
|.coom file appendix appears on every file that got encoded using the AES encryption algorithm, so the victim can differentiate locked files from un-affected data
|Files get encrypted and useless, the desktop gets changed to a ransom-demanding message wallpaper, and the text file with the same demand appears on the desktop and in various folders with encrypted files.
|Possible payload files
|EmailExtractor, Super Email Validator, contract.scr
|READ_IT.txt is the file that delivers a ransom-demanding message from the virus developers. This file contains information about payment, the amount, and sites where to purchase the Bitcoin. The similar message also gets set as the desktop wallpaper or as a lock screen
|Spam email attachments with infected files and malicious macro viruses embedded on the MS documents directly get send by hiding the content using names of legitimate companies, online shopping, or shipping platforms. These emails pose as notifications with financial data, so people open the attachments without thinking twice and infects the system without even noticing
|Coom ransomware removal can and should be performed using anti-malware tools that can possibly detect this threat and associated files, so the infection is fully terminated
|System files that get affected by this threat should also get repaired, and other virus damaged fixed, so rely on system optimization or cleaner tools like FortectIntego for this
Coom ransomware is an English-speaking users-targeting virus, but it can spread around the world. Especially, when the ransom note is short and specific. Each text file gets personalized with a particular name of the machine that the user has set and victims' ID that is generated by the virus when the encryption is performed on those files all over the computer.
This is the threat that mainly affects Windows devices but can be adapted to macOS later on, so you shouldn't think that your device is immune to cush crypto viruses when you use Apple devices primarily. Even though Coom ransomware focuses on encryption and affecting images, documents, video, audio files, and databases or archives, it still can damage system folders and functions without much effort.
When the encryption process is done, and all the chosen files get locked, Coom ransomware delivers READ_IT.txt with the following text:
YOUR FILES HAVE BEEN ENCRYPTED
Your USERID is USER-PC
To unlock your files send 0.015 BTC (about $150 USD) to the following
bitcoin wallet address:
Once you have sent the bitcoin, make note of your USERID above and the
transaction id of your bitcoin payment and go to http://188.8.131.52:11344/unlock.php
and you will be able to get your decryption key and the decryption tool.
If you are wondering how to purchase bitcoin easily, using paxful.com
with store bought gift cards is quick and easy, but there are many other ways
to buy bitcoin as well.
This message is followed by changes of the desktop wallpaper and additional lock screens to make people more scared into paying the ransom. However, this is the first, but not the only step in the Coom ransomware attack. Malware can easily access system folders and inject its own files there. Such parts of the machine, like Windows registry entries and startup preferences, get altered to make the virus running after each reboot and continuously. Coom ransomware - cryptovirus that asks for Bitcoin payments for alleged decryption tools that may not even exist or help with encoded data. If so, you can lose data and money permanently. Experts also note that you need to remove Coom ransomware as soon as possible because it makes the elimination and data recovery especially difficult since it manages to disable functions, install files and delete things needed for the recovery or other options.
When Shadow Volume Copies get deleted or security tools disabled, you may experience difficulties while trying to terminate Coom ransomware. This is why we offer to rely on automatic anti-malware programs and run them as soon as you receive the ransom demanding message.
Employing professional malware detection-based applications for the proper Coom ransomware removal gives you an advantage because all possible intruders and cyber threats get detected during the full system scan. Follow suggestions of the program and remove all indicated programs and possibly malicious files to terminate the infection completely.
This is not the option for Coom ransomware encrypted file recovery, but it is the most important step because you clean the machine fully and can then safely replace encoded files with safe copies or recovered data using third-party programs designed for that. We also have listed a few tips and options for file restoring below the article
As for affected files and other virus damage, you should get a system optimization program that can find and fix issues for you. You can do that with FortectIntego or PC repair software. Remember to fully repair crucial parts of the machine before adding your external device with file backups, because of possible secondary Coom ransomware encryption. Coom ransomware is the threat based on blackmailing and money extortion, so you should remove the malware as soon as possible instead of considering to pay.
Overlooking proper system protection and red flags lead to infections
You cannot notice the infiltration of this cyber threat because it manages to drop the payload file on the system directly without causing any symptoms or particular indications. It happens either when you install software from pirated or malicious sites, fall for scammy updating campaigns or don't pay needed attention to spam emails.
Antivirus programs can help avoid the installation of malicious applications or potentially unwanted programs if you keep them up-to-date and run more often. Pirating software is dangerous because you cannot see all the included files in the package and allow them to infect the machine without knowing.
However, the more common method of spreading ransomware is spam email campaigns that include file attachments filled with malicious macros and other scripts leading to infections like this. You should delete emails when you receive them out of nowhere, especially when the notification contains suggestions about financial details. Such MS documents only need one push of the button to enable the malware drop.
Clean the issues regarding the Coom ransomware infection and restore files yourself
Coom ransomware virus spreads the infection via payload droppers and malicious files triggering scripts and activities on the machine and in the background. You need to find all malicious files since those are the ones that control all the processes, encryption and triggers the damage.
When you remove Coom ransomware, you should take all the additional payloads and programs into consideration. This why automatic methods are more recommended and suggested by researchers, malware experts. Rely on SpyHunter 5Combo Cleaner, Malwarebytes, or anti-malware programs of your choice and run the full system check.
The professional system security program should indicate all the parts of this or additional viruses and suggest to go forward with Coom ransomware removal. When your machine is virus-free, you should run FortectIntego or a system optimizer that can eliminate virus damage too. Only then worry about data recovery.

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.
