This time we will take a look at the free antivirus program from the Microsoft called Microsoft Security Essentials.

You can download it from the official Microsoft site. The program is completely free, the only thing it validates is if you have a legal copy of Windows – you must run genuine Windows on your computer to install Microsoft Security Essentials.

The installation is pretty straigthforward, as one would expect from a program written by the same company that created the operating system, but if you are stuck, there is a help guide and an installation video available on the website. It should also be noted that Microsoft Security Essentials runs on Windows XP, Vista and Windows 7.

Now how about the protection of your system – is it good? Actually it is very good. It does its job of protecting your computer from viruses and it does not require a lot of your attention (meaning it is not asking you constantly what to do with various threats). But it can be a bit on the slow side when running a scan or quarantining a virus or other threat.

If you like Microsoft products and are looking for an easy to use free antivirus which only requirement is that you have a genuine copy of Windows, Microsoft Security Essentials might be the right choice for you.
