How to protect against the CryptoLocker malware

CryptoLocker is a malware which encrypts files on a computer and demands ransom for decrypting them. Files (documents, images, videos, etc.) are encrypted with a complex cryptographic code, which requires a key located on the malefactors' servers. As a rule, the ransom must be paid within the certain period of time, after which the decryption code claims to be deleted from the servers and restoring the files becomes impossible.

How the computer gets infected

  1. Through email messages You receive an email message with an attached .exe file, archive or image. The message usually imitates a notification or request from official institutions, delivery services, etc.
  2. By visiting an infected website Ransomware can get to your computer when you visit an infected website. Often, viruses are masked as offers to update commonly used software, such as Java, Flash Player, Adobe Reader, etc. which pops up on unsafe websites.

When you open an attachment in the message or when you click a suspicious link or download a file on a website, you risk infecting your computer with ransomware.

At the moment of infection no visible changes are made to the computer; the files are encrypted in the background mode. After the encryption process is completed, the screen gets blocked with the banner demanding payment in exchange to files decryption.

Shall I pay the ransom?

There is no guarantee that the files will be decrypted after you pay the ransom. Even if the malefactors send you the key, errors during decryption may lead to data loss.
