Microsoft Security Essentials is Microsoft's free anti-malware security software for computers still running Windows 7 and Vista. According to third-party 3rd party devs, Microsoft Security Essentials offers only basic malware protection, so you definitely will need an additional antivirus program. This application provides your PC with real-time protection against viruses, spyware, rootkits, etc. Microsoft Essentials can be used for both online and offline system scanning and cleaning tasks. If your computer runs Windows 8 or Windows 8.1, it doesn't need this security program, because it have pre-installed Windows Defender, which is an upgraded version of Microsoft Security Essentials, offering enhanced protection against rootkits and bootkits.
