On Borrowed Time: The Threat of Ransomware

"Ransomware" is a type of malware that holds files or computer operations for ransom.  In the most common scenario, ransomware will encrypt files on an infected computer and demand that the user pay for the decryption key. Ransomware presents an unusual threat in that simply removing it from the computer does not solve the problem.  When files have been encrypted, removing the ransomware does not make them available again.  The files must be decrypted.
