What is CTB-Locker ransomware
CTB-Locker – is a typical ransomware, that use well-known monetizing system. It encrypts documents and files, after this it offers decryptor for money (about 0.5 bitcoins). Also it renames files and adds .ctbl file format, creates AllFilesAreLocked.bmp (might be installed as desktop background) and DecryptAllFiles.txt files. We don’t recommend to pay money for this, because CTB-Locker may not help user after payment. We recommend to remove CTB-Locker manually and recover encrypted .ctbl files.
When infection starts, virus will show you a screen that will tell you how long it is to pay the ransom for decryption. Next, CTB-Locker creates a user ID for your infected computer, this user ID will be embedded in various file names. CTB-Locker creates an image file named AllFilesAreLocked in the My Documents folder
