Microsoft Security Essentials Automatic Virus Signature Updates

In one of our posts earlier today we talked about MSE command line utility MpCMdRun.exe. We also discussed that running it via Scripts or the build-in Windows Task Scheduler can come useful. In this post we are going to show how you can check for Microsoft Security Essentials Signature Updates on daily, weekly, or monthly basis using the Task Scheduler. Side Note: We are using Windows 7 Ultimate 64-bit.

First of all launch Task Scheduler from Start > All Programs > Task Scheduler and click Create Basic Task option. You can also launch it by typing Task Scheduler in the Start Search.

Basic Task

Specify the task name and description.

MSE Update 1

Next, choose when you wish to run the task. You can either run it daily, weekly, monthly, one time, when the computer starts, when I log on, or when a specific event is logged. We would recommend that you select either Daily or When the computer starts.

Task Schedular 2

Next select what you want to run when this task is executed. In this case, choose Start a Program.


Task Schdular 3

Now enter the full path of the directory where the MpCmdRun.exe is residing. You have to put SignatureUpdate command next to MpCmdRun.exe as shown in the screenshot below. So the full path becomes:

[Directory]/Microsoft Security Essentials/MpCmdRun.exe SignatureUpdate

task Schedular 4

In the final step, confirm the task details and click Finish.

Task Schedular Final

That’s it. Microsoft Security Essentials Signature Update will now run according to the specified schedule. There is no need to manually download the Virus definitions any more. ;)

One must be wondering why to create a task to update the virus signatures, does MSE not update the virus signatures? The reason is that MSE doesn’t update the virus definitions if Windows Update is disabled, so creating a task can be useful in such situations. Enjoy!

    I can find a way to minimize the task, I always get a black command line window popping up :(

    is there a way to solve this

    BTW I've got windows update set on automatic and always install updates, but MSE never updates without me clicking on the update button (he warns he's no updated in the tray area though)

    I can't find a way… sorry for the typo

      If MSE is not updating automatically, I would uninstall and then re-install.
      Mine updates once a day (but sometimes goes 2 days)

      I read that to get rid of the command line window that you should that you should change the name of the user account under security options.
      Double click on the task, select Action in the top bar, and then Properties.
      Under General tab, click Change User or Group.
      In the box “Enter the Object Name” type SYSTEM

      I have tried this but I was not around when the definitions updated, so I can't be sure it works yet !

        Thanks for that tip. It works perfectly under WinXP Home SP3. BTW, you can test run this or any task by right-clicking it and choosing “Run”. (Some system setups may also run the task by double-clicking it.)

    I’d rather NOT update this more than every 3 days.
    How do I INCREASE the delay between updates.?

      There are more than 1000 new viruses released per DAY. Why in the world would you like to be susceptible to all those viruses for several days????
