Microsoft Security Essentials is the antivirus program that I use and recommend (announced back in this post on October 25, 2010). In the past few days, a new version of Microsoft Security Essentials has been released – version 2.0. While it’s not mandatory, I do recommend that you get the new version (and in reality, you will probably end up getting it in a Windows update at some point anyway).
Upgrading to Microsoft Security Essentials 2.0 is pretty straightforward. You go and download the programs here, run the downloaded file to complete the installation, and then check your configuration to make sure everything is set up correctly.
There is a great new feature in version 2 – you can tell the program to only use a certain percentage of the computer’s resources when it’s doing a scan. This means that you can set it to scan even during a time when you will be using the computer, and it will have little or no effect on your work.
For full step-by-step instructions on how to upgrade to Microsoft Security Essentials 2.0, and how to make sure it is configured properly, I have created an instructional video. Watch the video here.
