Atomsilo Ransomware


Atomsilo is a virus program that attacks Windows machines, making the user files on their hard drives unusable. The purpose of Atomsilo is to harass its victims through the lockdown on their files in order to force them to pay a ransom.


The Atomsilo Ransomware will encrypt your files

Supposedly, once the victim pays the demanded amount of money, their files will be set free and they will be able to use them once again. At least this is what the Ransomware victims are told within a ransom message that the threat generates on the attacked computer.

The virus itself launches a process known as data encryption which is what allows it to make the targeted files unavailable. The data-encryption isn’t something that damages the computer in any way and the files affected by it stay intact after it is finished. The only thing the encryption does is it makes the files it affects unrecognizable to any program the victims may use to try to access their files. The encryption rearranges the code of the targeted files, turning them into unreadable pieces of data no program can open. However, if the correct decryption key is applied to those files, they will become accessible again. Needless to say, this key is the thing offered to you in exchange for the money you send as ransom.

If your PC has been hit by Atomsilo and you’ve lost access to some highly important files that you need, then you should carefully consider what your next action would be. Know that, usually, paying the money is not an advisable thing to do due to the risk of not getting the key after the payment, in which case your money would have been wasted in vain. There are some alternative ways you can approach this unpleasant situation and we will tell you about them down below.

The Atomsilo virus

The Atomsilo virus is a threatening malware program capable of encrypting the files of its victims, thereby making them inaccessible. The Atomsilo virus is designed as a money-extortion tool and it won’t release the files until a ransom is paid to the hackers.

The paying of this ransom, however, is not the best solution, as was already mentioned. Many hackers behind Ransomware infections like Wiot, Edfc don’t really intend to send the decryption keys to their victims and only want to get the money without providing a working decryption solution.

Unfortunately, the alternatives also don’t give any guarantee about the recovery of the locked files. However, if you follow the instructions we have included in our guide, you should be able to at least clean your computer by eradicating the virus. Also, the suggested recovery alternatives we have prepared for you are free and they may still work in some cases.

The Atomsilo file decryption

The Atomsilo file decryption is a procedure that requires a special access key to make the encrypted files accessible again. The key for the Atomsilo file decryption is stored on the hackers’ computers and they offer it to you against a ransom payment.

If, however, you decide to opt for the alternative methods, you may still get to restore some of the data while not needing to pay anything to the criminal blackmailers behind the Ransomware.

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).



Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    After you open their folder, end the processes that are infected, then delete their folders. 

    Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Type msconfig in the search field and hit enter. A window will pop-up:


    Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

    • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.


    Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

    Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

    Type each of the following in the Windows Search Field:

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
