What is CryptoLocker?
CryptoLocker is what is known as ‘ransomeware’. Basically this means that it infects a computer and restricts access to it in someway. They often also constantly harasses the user with annoyances such as popups. The aim of the software is to make the user pay a ransom to the operators of the malware to remove the restrictions.
CryptoLocker is spread via infected email attachments or by computers that are already infected acting as a ‘botnet’.
How do I know I’m infected?
Usually the sign of infection will be messages asking you to pay money (usually in the region of 400 USD or Euros) to an anonymous pre-paid cash voucher (there are many of these services and it varies from infection to infection). There is often a time limit on these payments, typically between 72 and 100 hours.
