CryptoWall 2.0 is a computer infection known as ransomware that encrypts files (makes them unreadable) on any Windows computer, including XP, Vista, Windows 7 and Windows 8. Immediately after CryptoWall infects a computer it starts to automatically seek out any data it can find and encrypt it, making it completely inaccessible to the computer user. One of the most effective safeguards against getting infected by the CryptoWall 2.0 virus is to not open attachments from any source you can’t personally verify via the telephone. Call the person or organization that sent you the attachment and ask them, “Did you send me an email with an attachment?” Most will say ‘no’.
