What is CryptorBit ransomware?

CryptorBit is a dangerous  malware categorized as ransomware or a cryptovirus that targets all versions of Microsoft Windows including Windows XP, Windows Vista, Windows 7, and Windows 8. When infected, this ransomware will scan your computer and encrypt any data file it finds regardless of the file type or extension.

The CryptorBit virus locks a computer system, encrypts the files on the machine, and demands a fine to de-encrypt the files and release the computer. The CryptorBit virus will create a HowDecrypt.txt file and a HowDecrypt.gif in every Windows folder that CryptorBit encrypts. The GIF and TXT files that download alongside the CryptorBit virus will contain instructions to access a fraudulent payment website that pay the fake ransom. The CryptorBit payment site is located on the Tor network and you can only make the payment in Bitcoins.

When CryptorBit encrypts a file it does not actually encrypt the entire file, instead the CryptorBit virus replaces the first 512 bytes of the file.

The message displayed by the Cryptorbit virus should be ignored as files are not fully encrypted and the message is utilized in order to scare victims into paying an unnecessary ransom. If you are infected with Cryptorbit malware do not pay the fine and do not click any links or available navigation buttons! Instead use the free removal instructions below or seek professional assistance.
