Our AVG Business license is expiring and instead of renewing the license for $500, I would rather go with something free on the workstations (not the server). We have about 15 or so computers, only a few having limited internet access. I do not need to centrally manage them. Would MS Security Essentials work fine on them as long as I do a little training on best practices to the people that use the internet? If not Essentials, what other antivirus solutions are there that are okay for a business to install? What else should I consider besides just antivirus?
