Microsoft Security Essentials
Microsoft Security Essentials (MSE) is an antivirus software (AV) product that provides protection against different types of malicious software, such as computer viruses, spyware, rootkits, and trojan horses. Prior to version 4.5, MSE ran on , Windows Vista, and Windows 7, but not on Windows 8 and later versions, which have built-in AV components known as Windows Defender. MSE 4.5 and later versions do not run on Windows XP. The license agreement allows home users and small businesses to install and use the product free-of-charge. It replaces Windows Live OneCare, a discontinued commercial subscription-based AV service, and the free Windows Defender, which only protected users from spyware until Windows8.
