CryptoLocker

Malware

CryptoLocker is a Trojan horse that infects your computer and then searches for files to encrypt. This includes anything on your hard drives and all connected media — for example, USB memory sticks or any shared network drives. In addition, the malware seeks out files and folders you store in the cloud. Only computers running a version of Windows are susceptible to Cryptolocker; the Trojan does not target Macs.
