Remove .Bora Ransomware Virus File (+Recovery)

.Bora Virus


.Bora is a variant of a malicious software category known as Ransomware. An infection with .Bora is generally invisible until the malware completes its agenda.

When the .Bora Virus is finished encrypting your files it will display this message in a _readme.txt file

If you are on this page, the hackers behind .Bora have most likely notified you that your files have been encrypted. They have also probably told you that if you ever want to access those files again, you should pay a fixed amount of money as a ransom. And, indeed, if a scary ransom-demanding message has suddenly appeared on your screen, you have probably lost the access to most of the data on your computer.

Nevertheless, don’t be afraid – in this guide, you will find detailed instructions on how to deal with this situation, and although we can’t promise a 100% recovery, it certainly won’t cause any harm to give our guide a try, and most importantly, to remove .Bora from your system. 

The .Bora virus

The .Bora virus is a serious infection which can lock-up some of your files by encrypting them. Since the encryption process used by the .Bora virus isn’t harmful to the files, most antivirus programs cannot detect the infection.

Once it has nested inside the system, the cryptovirus like .Bora, .Reco, .Noos will gradually begin encrypting your documents, images, videos, audios, and other frequently used digital data. When the encryption process is completed, the Ransomware will then use a message like the one described above to demand a ransom. To be precise, the ransom is demanded for a special decryption key, which is kept with the hackers, and is the only thing that can unlock the sealed information.

The .Bora file encryption

The .Bora file encryption is likely to remain on the affected files even once the virus is removed. In most cases, the .Bora file encryption can be reversed only with the application of the corresponding decryption key.

However, how to proceed if you don’t want to pay a ransom to some anonymous hackers, or simply don’t have the required money? Our first advice is to remain calm, and explore your options. Understand that you are dealing with cyber criminals who have had no moral issue with infecting your computer, and demanding money from you. Therefore, there is no reason to believe anything they promise you. Therefore, it is much more advisable to explore some other alternatives, which do not involve giving your money to some anonymous blackmailers.

For instance, in the removal guide below, you will find some file-recovery suggestions which our “How to remove” team is offering for free. There are also easy-to-follow steps on how to detect, and remove .Bora from your system manually, or with the help of a professional removal tool.

Of course, we can’t promise that this will restore all your files, and get everything back to the way it used to be, but before you surrender to the hackers, and pay the ransom, it is a good idea for you to try to recover your system by whatever free means are available to you.
