Webroot is a very easy to use and effective software. It is quick to use, does the job well. My only complaint is when I renewed, I ended up buying a new subscription instead. It was a little confusing.
Seems to work fine, used for many years and never had a malware experience that I know about. My only complaint is with the renewal process--- I have often been notified of end of subscriptions early, then paid for a second service for the same computer and got both renewals. Also while it is supposed to be good for three devices, my new HP laptop will not even open the webroot website, or rather opens it then immediately covers it in grey shade, making mouse ineffective.
