Sophos Home includes all the features of Free Mac AV with a sleek new user interface that allows you to protect all computers in your home (Mac and Windows) from a single interface. And yes, it’s still free. When downloaded and installed, this new interface, called Sophos Home, replaces the existing Sophos Antivirus application.
There is a totally new interface, in fact, two new interfaces. One is an app that runs on the computer and the other is a web interface accessed at home.sophos.com for which you are required to create a free account. Both will allow you to run a scan on the computer, but the web app is where you define or configure how Sophos checks for trouble.
From the computer app, you can only scan the computer or turn on or off a protection. From the Web interface, you have complete control of how each of your computers are protected.
There are three kinds of protection. These are Automatic Virus Protection and Web Protection. The virus protection can also check for Potentially Unwanted Applications in real time and prevent them from being installed - and you an override this if you really want to install an app that you are sure will cause your computer no harm.
In the web protection, there are three categories. These are General Interest, Social Networking & Computing, and Adult & Potentially Inappropriate. For each category there are numerous items to select one of three levels of protection for each item. These are Allow, Warn, and Block.
It is still recommended to do a full scan after installing just to let Sophos know it has done that at least once. Thereafter, it may not be needed to do another full scan since the system is being protected in real time.
The only caveat that I might mention here is that blocking some items can result in your not being able to view attached images that someone sends you. Tinkering is allowed.
