Microsoft Security Essentials is our favourite antivirus software for Windows, and a new version is out that's even lighter and easier to use than ever. Here's what's changed.
MSE veterans won't notice a lot of huge changes in this version, but certain interface elements have changed slightly — the icons along the top are gone, and certain words have changed a bit to make the program easier to use. The "Real-Time Protection" setting is now an all-or-nothing checkbox, and SpyNet has been renamed to the Microsoft Active Protection Service to make a bit clearer what it actually does. Microsoft has also baked in some performance improvements and better detection powers.
Microsoft Security Essentials is a free download for Windows only. You can get the new version through Windows Update, or on its home page at the link below.
