Microsoft Security Essentials is an antivirus and malware scanning product that integrates with Windows Update. As a result, it's historically been easy for users to install and maintain. The built-in Control Panel takes care of most configuration options and Microsoft has extensively tested the software to ensure that it's compatible with any machines running their operating system.

That means it tends to perform quite well. Users will sometimes install an always-on security program only to find that it starts to slow down the system considerably after a couple of reboots. Microsoft Security Essentials doesn't normally have this problem. In fact, it takes advantage of several built-in Windows assets, like the windowing toolkit, to make all of its interface elements move more fluidly than is normally seen.

As a result, it might be a great option for those who can't run a more complex piece of software due to hardware limitations. Redmond's premier security product works on any machine that's capable of running the underlying operating system.

That being said, MSE provides real-time protection and constantly monitors every new file that's stored on your computer. It will check all executable objects against a database of signatures and flag anything that looks suspicious.

As well as traditional virus programs, MSE can detect certain types of worms as well. Depending on the specific settings you pick when you first install the software, it can make System Restore points before removing any specific piece of malware. This can drastically reduce the risk of problems caused by false positives.

Whenever the software makes any kind of change to the system configuration, users are given the option to roll it back with nothing more than a reboot.
