Overview
There are a host of nasty intruders on the Internet including viruses, trojans, worms, and spyware. Microsoft Security Essentials 64-bit offers award-winning protection against these intruders without getting in your way. MSE software is built for individuals and small businesses, but it’s based on the same technology that Microsoft uses to protect giant businesses (security products like Microsoft Forefront, Malicious Software Removal Tool, and Windows Defender).
Overview
MS Security Essentials is a free antivirus program developed by Microsoft Corporation. It offers essential protection against malware, viruses, spyware, and other potentially harmful software. With its user-friendly interface and real-time protection, it aims to ensure the security and stability of your Windows-based systems.
It received great recognition for the protection it offers: the VB100 award from Virus Bulletin Ltd., Checkmark Certification from West Coast Labs, and certification from the ICSA Labs. Downloading and installing It is free and easy. Once you have installed it, the software updates automatically once a day.
It uses green, yellow, and red color codes to designate the security status of your PC and a color-coded icon in the taskbar tells you at a glance if your attention is needed. It’s simple—when you’re green, you’re good. However, if there’s a red or yellow threat, Antivirus software will alert you and recommend what to do (you can act directly from the notification area without having to enter the application).
The program runs quietly in the background. You’ll only be alerted when there are specific actions to take. When you’re away or busy, Security Essentials can take the default action on your behalf and you can open the program later to review and undo those actions if you wish.
This security software is efficient and compact. Scans and updates are scheduled to run when the PC is idle and the software works in a way that your PC is still snappy when you’re using it. All this makes Microsoft Security Essentials friendly for all sorts of computers—your old PC, your new PC, your laptop, as well as your little netbook.

FAQ
Why has Microsoft Security Essentials been discontinued?
Microsoft Security Essentials is no longer available for new installations because it is tied to the Windows 7 operating system, which is no longer supported. Microsoft has shifted its focus to Windows 11/10 and recommends users transition to this newer operating system for the best security options. As a result, the availability of Microsoft Security Essentials has ended.
Will Microsoft Security Essentials still work on my system?
While new installations of Microsoft Security Essentials are no longer possible, existing installations will continue to function. Microsoft will continue to provide signature updates for Microsoft Security Essentials until 2023. These updates ensure that the software remains effective in detecting and removing known threats. However, it is important to note that without ongoing support and updates, the software may become less effective over time, leaving your system more vulnerable to emerging threats. Therefore, it is highly recommended to upgrade to Windows 11/10 and use Windows Defender (Windows Security) Antivirus, which is the successor to Microsoft Security Essentials and offers enhanced security features.

Can I use Microsoft Security Essentials alongside other antivirus software?
Answer: It is not recommended to run multiple real-time antivirus programs simultaneously, as they may conflict with each other. Uninstall any existing antivirus software before installing "MSE".
