Fedasot ransomware (Virus Removal Instructions) - Bonus: Decryption Steps
Fedasot virus Removal Guide
What is Fedasot ransomware?
Fedasot ransomware is crypto malware that initiates a variety of system changes to encrypt personal user files
Fedasot ransomware is a file locking malware that belongs to STOP (Djvu) virus family
Fedasot is a file locking threat that was discovered when victims reported the infection in early May 2019. Belonging to the STOP/Djvu virus family, this ransomware focuses on money extortion and demands $980 or $490 payment in Bitcoin or any other cryptocurrency.
As soon as Fedasot ransomware enters the machine, it performs a variety of system changes, contacts C2 server, and then begins the file encryption process that is performed with the help of AES or another algorithm. During this process, the malware displays a fake Windows update pop-up that is developed to mislead the victims and prevent the interruption of the process.
Once the process is over, each of the personal files like pictures, music, databases, documents, and others are marked with a .fedasot appendix. Unfortunately, from this time victims are unable to open any of the data affected by the virus. Instead, they can access a ransom note _readme.txt that explains to users what happened to their machines and what to do next.
Just as in previous STOP variants, crooks behind the threat ask users to contact them via the @datarestore Telegram account or firstname.lastname@example.orgemail@example.com email addresses. If you are infected with the virus, you should immediately remove Fedasot ransomware with the help of the instructions that can be found in the bottom section of this article.

There are a variety of ways one can get infected with Fedasot virus. The most common infection methods used by hackers are:
- Spam emails;
- Exploit kits;
- Cracks or keygens;
- Pirated software installers;
- Web injects;
- Fake updates, etc.
Once inside the system, Fedasot ransomware performs a variety of changes to the Windows operating system. For example, it modifies Windows registry to gain persistence and deletes Shadow Volume Copies to prevent file recovery after Fedasot ransomware removal.
These modifications to the system help the malware to perform file encryption without interruptions. Unfortunately, users then find out that are unable to view documents, pictures or any other data located on their machine. Instead, they can open the _readme.txt ransom note which reads:
Don't worry my friend, you can return all your files!

Depending on where you live, $980 or $490 might be a large or small sum. Regardless of the price, you should ignore the message from cybercriminals and never contact them, as chances of being scammed remains. Besides, paying threat actors will only prompt them to infect more victims and create new versions of Fedasot ransomware.
Thus, use anti-malware software to terminate the Fedasot virus, scan your computer with RestoroIntego to repair the infected system files and only then attempt file recovery. You can connect your backup device or retrieve data from virtual storage.
If you did not have backups, restoring files might be almost impossible, unless the encryption process took place when your machine was not connected to the internet. Nevertheless, we suggest you try using third-party software as it might be able to recover at least some of your files.
Fedasot ransomware is a type of malware that locks up users' files and demands ransom of $980/$490 to be paid for the decryption tool
Take care of your online safety to avoid ransomware infections
While avoiding computer viruses 100% might be impossible, there are several precautionary measures that you could make use of – it would reduce the chance of the infection to a minimum. Nevertheless, installing anti-malware software and updating it on time is not enough, especially if being careless online.
Anti-malware software is a great tool to protect yourself from already known viruses, although most paid programs use machine learning technology, which can recognize suspicious patterns of completely new malware. Nevertheless, hackers are intelligent people, and they are always looking for new ways to trick security software.
Therefore, besides using the anti-virus application, you should also:
- Keep your Windows updated, along with all the installed programs;
- Use caution when handling spam emails, especially those with attachments or hyperlinks (be aware that some phishing emails manage to bypass the built-in scanners and end up in your Inbox);
- Use ad-blocker when visiting high-risk sites (torrents, adult-oriented, third-party downloads, etc.);

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
