CryptoLocker "Your personal files are encrypted!" removal guide
What is CryptoLocker?
CryptoLocker is a ransomware virus created by cyber criminals. The virus is distributed using 'exploit kits', which infiltrate users' computers using security vulnerabilities detected within outdated software. Common sources of exploit kits are infected email messages, malicious websites, and drive-by downloads. Note that exploit kits rely on outdated software in order to infiltrate systems, therefore, keeping your operating system and all installed programs up-to-date greatly reduces the risk of infection by ransomware viruses.
After successful infiltration, CryptoLocker encrypts files on the infected machine and demands payment of a 300 USD or 300 Euro ransom in order to unblock the computer and decrypt the files. Cyber criminals order this ransom payment using Ukash, cashU, MoneyPak, or Bitcoin. Note that paying this fine is equivalent to sending your money to cyber criminals with no guarantee that your files will be decrypted. Owners of the infected computer are advised to remove this virus and recover their files from a backup.
Files encrypted by this ransomware get ".encrypted" extension. Notice that unlike the original Cryptolocker this ransomware doesn't remove the Shadow Volume Copies of the stored files, thus it's possible to use Windows restore feature to regain control of encrypted data.
Victims of TorrentLocker can use a tool (called 'TorrentUnlocker' created by Nathan - DecrypterFixer) to decrypt their files. More information on how to use this tool available at bleepingcomputer.com website.
