Sophos CEO sounds the alarm on enterprise ransomware attacks



Ransomware is increasingly becoming a problem for companies, and the CEO of a leading computer security company says he fears 2017 could see entire companies shut down until they pay up, or risk losing all their data.

Ransomware works by infiltrating a computer with malware and then encrypting all the files on the disk.
