Easy to use, easy for our team of nurses who are not computer experts at all! The only thing I have found difficult so far has been finding time in my schedule when they can be used during work hours (which isn't often). If you know how computers function this program will make it very simple as long your PC or Mac meets their requirements regarding speed/power etc.. We've had no issues with viruses but we were told by another employer using different software about an issue where someone was downloading virus's from other people through email attachments which could potentially infect us if opened without cautionary measures taken beforehand - something i'm sure most employers would want resolved anyway?
