I like how simple and easy is to use Webroot, you can install it and manage all the devices in your infrastructure through the console. It is technically the best virus protection and hassle free.
Nothing at the moment, i hope they don't mess anything in the future updates.
Give it a try and you will be amazed after few weeks that how simple easy and robust webroot is to protect your network environment.
The biggest threat we were experiencing was ransomware emails coming through and in early 2015 we got hit with it. Smart enough we reacted proactively and stopped it by not allow it to spread through the whole network only a couple of PC's were infected. After that I gave a trial to webroot and in less than 3 weeks bought 125 licenses then again increased to 175 licenses including mobile devices. Since then we have been protected from all sorts of ransomware variants which are being circulated in the wild.
