Cryptorbit "Your personal files are encrypted!" removal instructions

What is Cryptorbit?

The Cryptorbit ransomware virus infiltrates users' computers using infected email messages and P2P networks. After successful infiltration, this malicious program encrypts files (*.doc, *.docx, *.xls, *.ppt, *.psd, *.pdf, *.eps, *.ai, *.cdr, *.jpg, etc.) stored on users' computers and demands payment of a 0,5 BTC (Bitcoins) ransom in order to decrypt the files. At time of writing, 0,5 BTC was equivalent to approximately $400 USD. This ransomware is identical to a previous variant named Cryptolocker. PC users should be aware that, whilst the infection itself is not complicated to remove, decryption of files affected by this malicious program is impossible without paying the ransom. At time of research, no tools or solutions capable of decrypting files encrypted by Cryptorbit were available.

Immediately following infection of the user's operating system, this ransomware contacts a command-and-control server and generates a public key used to encrypt the data. After successfully encrypting the detected files, Cryptorbit displays a message (screenshot below) explaining how users may retrieve their files. Note that the private key, capable of decrypting the files, is stored within Cryptorbit's command-and-control servers, which are managed by cyber criminals. The best way to deal with this ransomware is to eliminate it from your computer and restore the affected files from a backup.

The existence of ransomware infections such as Cryptorbit are a strong argument to maintain regular backups of your stored files. Note that paying the ransom as demanded by Cryptorbit is equivalent to sending your money to cyber criminals - you will support their malicious business model, and moreover, there is no guarantee that your files will be decrypted. To avoid system infection by ransomware, express caution when opening email messages, since cyber criminals use various catchy titles in order to trick PC users into opening the infected attachments. Examples include, "Voice Message from Unknown", "Important - attached form", "Payroll Invoice", "New contract agreement", etc. Recent research shows that cyber criminals also use P2P networks in an attempt to trick PC users into downloading Cryptorbit.
