Ransomware

A computer attack that's been observed on the Eastern Michigan University campus may also pose a threat to your computer.  

The university is warning of so-called "ransomware" called CryptoLocker, which EMU spokesperson Geoff Larcom says poses a serious threat.

Lacom says the attackers can grab your files, encrypt them and lock them away. The owner is then forced to pay a ransom to have their files unencrypted and returned.
