Microsoft Security Essentials, the new antivirus from Microsoft, has received many positive reviews around the web since it’s launch. In recent comparative tests against established commercial and free antivirus applications, Microsoft Security Essentials came out with flying colors. If you are curious to try out this new antivirus, there is one thing you should know before you start downloading it - Microsoft Security Essentials can update it’s virus definition files only if you have Windows auto update enabled.
Many Windows users have auto update turned off by choice. Once Windows update is disabled, Microsoft Security Essentials doesn’t update any more. The only workaround is to manually download the latest virus definition files. But that’s a tiresome job since MSE updates daily and each virus definition file is a hefty download (~50MB).
MSE Update Utility is a small tool written in .Net that allows you to automatically update Microsoft Security Essentials even if you have Windows Update turned off.
From the main window you can select the update intervals, there are four options given – Daily, Weekly, Monthly, or Startup. It notifies you once the update is completed.
You can either keep MSE Update Utility always running in the background, which is the way it’s intended to be used, or manually launch the program whenever you feel like updating the virus definitions.
