A new version of Microsoft Security Essentials has just been released for those using Windows XP with Service Pack 3, Windows Vista with Service Pack 1 or 2 and Windows 7 computers.

Microsoft Security Essentials is a free security program that provides real-time protection for your home and work computers.

If you have Windows 8.1, you can’t use Security Essentials. Windows 8 and 8.1 come with Windows Defender that provides the same built-in protections for Windows PC.

Windows Defender is already installed in Windows, so you don’t have to do anything. Windows will also automatically update it as well as its definition files.
