With the current threat from ransomware and cryptolocker virusses, every business owner needs to ask himself: "Am I protected". Does your security software provide adequate protection against the threat.
The top names are Avira (my preference), Kaspersky, Bitdefender.

In pcs and laptops I can suggest installing Ransomfree from Cybereason (free) - It creates an environment that makes the virus believe the computer is already infected/encrypted, so it leaves it alone. There is no 100% guarantee but it has worked well everywhere I installed it: PC World reviewed the software here: http://www.pcworld.com/article/3150748/security/this-free-software-protects-your-pc-against-ransomware.html
