A crypto virus is a type of ransomware virus like Locky or Cryptowall that encrypts files on a compromised computer and demands a ransom in return for a decryption code.
Crypto virus attacks are on the rise, with as many as 4,000 attacks each day and more than $1 billion in ransom paid each year, as estimated by the U.S. government.
