Microsoft Security Essentials delivers powerful antivirus solutions for Windows 7 and Windows Vista without the complexity, cost and technical jargon found in other PC antivirus software.

Whether you use the Internet for personal or business use, operating your digital life without the security of antivirus software is like playing a deadly round of Russian roulette. While you may think your emails and frequently visited websites are safe, security threats are lurking just around the corner.

As malicious attacks and hackers adopt advanced techniques, all it takes is a single click on the wrong link to have your entire digital life infection with spyware, malware and ransomware.

Avoiding infection from one of the countless threats requires understanding how to safely engage with the digital realm. However, sometimes this isn’t enough to thwart advanced hacking methodologies. To keep your computer safe from harm, you must use an effective antivirus software. But, as many computer owners understand, finding your best solution is easier said than done.

Microsoft Security Essentials was developed to provide Windows users a stable, easy and effective way to safeguard their computer from malicious attacks. Designed specifically for Windows 7 and Windows Vista, this native antivirus solution is ideal for casual computer users.

Powerful Features for Baseline Antivirus Protection

When identifying the best antivirus software for you, it’s imperative to understand how you use the internet. Microsoft Security Essentials was designed to provide a user-friendly interface for non-professional users. If you primarily use your computer to watch videos, email friends and family or online shop, then Microsoft Security Essentials is ideal for you. However, if you engage in more professional grade activities, you may find its capabilities lacking.

Although this program isn’t as potent as more robust antivirus solutions, this doesn’t mean it’s incapable of safeguarding your digital life. Its advanced architecture delivers deep-level file scanning without the bloat of more advanced software. Because of its native integration into the Windows operating system, it delivers complete monitoring without slowing down your computer.

The Features of Security and Effective Monitoring

Microsoft Security Essentials features a straightforward tabbed designed. Explore the status of your computer, update spyware and virus definitions and manipulate how the software seeks out threats. The biggest difference between Microsoft Security Essentials and other antivirus software is how it treats infected files. Instead of “cleaning” the file by removing the malicious code, MSE deletes the entire file from your system.

You can choose between three different scanning options, which include:

  • Quick - Ideal for fast scanning of your most important files
  • Full - Scans your entire computer for malicious code and infected files
  • Customized - Lets you choose when and how the program should scan your computer

Other features include automatic virus definition database updates and a system restore point, which allows you to restore your computer to a previously saved version. Overall, Microsoft Security Essentials is a perfect solution for casual computer users looking for an easy, yet effective, antivirus solution.

Microsoft Security Essentials protects your computers from common viruses, spyware and malware. Genuine Windows home users can download and install the software free to protect their system. The 64-bit version works more efficiently than the 32-bit version. However, you must have a 64-bit operating system to use the software.

Key Features

Microsoft Security Essentials supports all versions of Windows starting with Windows XP. The software is also available in 33 languages and provides you with quiet non-intrusive background monitoring. Some security programs alert you and interrupt your work with unneeded notifications. Microsoft Security Essentials takes care of problems in the backgrounds and only alerts you to severe threats. The download provides protection against malware that can slow down your computer, use your computer to send and receive malicious communications and protect your data from corruption.


One of the primary goals in the development of Microsoft Security Essentials was to create a program that protected computers without slowing them down. Many protection suites use up a large number of resources and end up slowing down a system more than the actual infection. To circumvent this, Microsoft ensures that you only get alerts when a specific action needs to be taken. If you are busy or away from the computer, the program takes the default action to resolve issue and allows you to undo any changes made when you have time to look at the problem. The software runs extensive scans and downloads updates only during idle times.

Simple Interface

Microsoft Security Essentials doesn't require a masters degree in technology to set up and run the software. Upon installation, the software is ready to use and immediately starts protecting your system. When you need to do something, the software will let you know. Because it's developed by Microsoft, it integrates seamlessly into your operating system. Viruses, worms, trojans and spyware are automatically detected and quarantined to protect your system. It's the only protection you will need for your system. Some advanced users may wish for more detailed configuration of the firewall rules and advanced scanning options. However, for users that want to set it and forget it, Microsoft Security Essentials provides robust and effective protection that rivals many commercial antivirus programs available on the market.
