CryptoLocker is a new variant of ransomware that restricts access to infected computers and demands the victim provide a payment to the attackers in order to decrypt and recover their files. As of this time, the primary means of infection appears to be phishing emails containing malicious attachments.
This malware may come disguised as a FEDEX or UPS niotice or a Amazon order or as another online retailer. Your best bet is to disregard the link and go directly to the site itself and look there. If you have nothing of importance on your drive this will not affect you if you are targetted but if you have docs, pictures or files of importance there is NO REMOVAL procedure. You will have to pay.
A new malware spreading around the Internet in recent months holds every file on a computer for ransom. Unless the user pays $300 in bitcoins to the hacker responsible for the infection within 100 hours, the hacker threatens to forever deny the user access to his or her files.
The malware, which is known as CryptoLocker, is not just an empty threat. If the hacker's demands aren’t met, the computer files get cryptographically locked, making it almost impossible to access them. A ticking clock showing the time limit makes CryptoLocker just a bit more terrifying.
