Hi, my name is ***** ***** I'll be happy to help you today!
Is your current subscription for 3 devices/1 year?
Okay, thank you.
There is no way to add a fourth device to a three-device subscription, so what you'd need to do is purchase a single device subscription for your fourth computer.
You can do that from the Webroot website at www.webroot.com and you'll be covered for a year. If you want to bring all the devices in line under the same subscription, then my recommendation would be that in November 2017 instead of renewing your three-device subscription, purchase a 5 device subscription that will cover all your machines.
I hope that makes sense. Let me know if you have any other questions on this.
