As far as I can tell it works well
As far as I can tell it works well. It works in the background, and I never notice it. I rely on professional advice and reviews. Sophos was recommended over my previous (AVG) . Recommended by the software/computer store where I purchased the new laptop. It is important to me to be able to use it on multiple devices. A good product that I can share across the devices in my home. Saves me money and frustration.
