The users of Microsoft Security Essentials 4 (MSE4) have been quite satisfied with the product because of its effectiveness and performance. If you have installed MSE on your Windows computer, you will barely realize that it is installed and running. Microsoft Security Essentials 4 got a performance score of 99.3 in AV-Comparitives latest performance tests. It was almost close to 100% in tests like copying files, archiving/unarchiving, installing/uninstalling application, encoding/transcoding, launching applications and downloading files from the Internet.
Overall, Microsoft Security Essentials 4 is a handy antivirus from Microsoft. It comes absolutely free of cost and can be installed in Windows Operating System. The only catch is that the Windows should be genuine. Otherwise if you are using a pirated version of Windows, this antivirus will not let you work anyway.
Microsoft has released a new version of MSE. The latest version becomes Microsoft Security Essentials 220.127.116.11. Before releasing the final version of MSE 4.2, Microsoft released a Pre-release version which was also available for download but the final version came out shortly announcing the Pre-release version.
Although I have tried hard to find a changelog of the latest version of Security Essentials 4.2, I haven’t been able to find one. So I will not be able to tell what has been added to the new release of MSE. But since keeping updated is the best strategy to survive on the Internet, you should update your installation of Microsoft Security Essentials to 18.104.22.168 for now.
If you are a Windows 8 user, Windows Defender does the same job as Microsoft Security Essentials. Windows 8 users don’t need to install MSE. They will automatically get the latest version of Windows Defender if they have automatic updates enabled.
