Btos Virus


Btos is a dangerous Windows virus of the Ransomware family that locates the most commonly used files in the computer and locks them. The goal of Btos is to make its victims send money to its creators in exchange for the release of their files.


The Btos Virus will encrypt all your files with the .btos extension.

The creators of this malware threaten that if the victim doesn’t send the demanded ransom money within a given period of time, the demanded sum would double or the “offer” of paying for the data’s release would no longer be available. If you have recently found yourself in a similar situation and don’t know what course of action to follow, we will tell you about the possible options you can choose from at the moment. However, one thing we must make clear right away is that the recovery of your data cannot be guaranteed no matter what you do. Some of the potential solutions you can try may allow you to bring back some of your data, while others may turn out to be utterly ineffective in your case. The main thing to understand here is that the ransom payment should really only be considered if there are no other options left and if you simply cannot afford to lose the locked data. In all other cases, paying is highly inadvisable.

The Btos virus

The Btos virus is a virus infection that belongs to the widespread Ransomware category of computer threats. The Btos virus blocks access to important files on the attacked machine and tells its victims they need to pay a ransom if they want their files back.

The main reason we recommend that you avoid paying the ransom money is that the hackers’ promises of restoring your data cannot be trusted. You could send the money only to realize that you would still not be allowed to regain access to your files.

If you are in the situation where Btos has taken your data hostage and you really need those files back, our suggestion is to turn to the removal guide you will find right below this article. The steps there will help you remove the virus, thereby making sure that no more of your files will get locked. After the infection is removed, you can move on to the alternative recovery options that will be present in the second segment of the guide.

The Btos file decryption

The Btos file decryption is the main method for restoring files locked by this virus. However, the Btos file decryption requires a special key to complete and that key is only present on the computers of the criminals behind this virus.

That being said, if you are lucky, you may manage to get around the need for decrypting your files or maybe find a custom decryptor tool for this virus, that you can get for free. We have a list of a big number of such free decryptors on our site as well as some other recovery suggestions, but before you get to them in the recovery segment of the guide, you must ensure that the infection is no longer present in your PC.
