Just a little snippet from the article may get you thinking

How did I come about such an exploit you may ask?  Downloading actor images, and meta data via the MetaBrowser utility!  I never imagined I would run across an exploit in such a way but there is also a good chance that it’s just a false positive.  I don’t blame MetaBrowser for it but should we be concerned?

about the need for an AV solution for your WHS.  You may not access the web through a browser on your WHS, but if a utility like My Movies for WHS looks for meta data, it might just grab more than it intended.

Food for thought…

Does WHS need AV? Here’s a Good YES Reason

The first thing we’ll need to do is head over and download and install the latest trial version of intelliremote. This latest version fixes some issues that cropped up with Windows 7, so if you’ve got a previous version installed be sure to remove it and upgrade to this version. The trial version can be used for 30 days and the full version will set you back $24. This modest price will is likely worth it for most Media Center enthusiasts simply for the ease of use that Intelliremote provides as well as the fantastic support evident on their forums.

Once Intelliremote is installed we’re going to perform one more quick fix to enable the program to take control of the system once inside Media Center. By default Windows 7 Media Center takes control of the input device and overrides any other program’s preferences once inside the Media Center program. To disable this we need to open up the Services and disable the Human Interface Device Access service.

To do this open Control Panel, System and Security, Administrative Tools and open the Services application. Locate the Human Interface Device Access listing, right-click the entry and select properties. Inside the properties dialog select Disabled under startup type and Stop the service using the Stop button. Press OK to save your changes and exit the properties and Services application.

Now let’s open up the Intelliremote program from the programs menu. Then open the Customize options from the system tray icon by double-clicking or right-clicking and selecting Customize. This brings up the options to set the buttons on your MCE remote to perform any action you’d like.

Let’s get started by selecting the Media Center icon on the left then choosing the MCE Videos button from the listing just to the right. Next press the Learn Code button and on your MCE remote press the appropriate button. If Intelliremote has detected the input properly a Success message should appear briefly then close the dialog. Afterward you can establish the action you’d like that button to perform.

For example if you’d like the MCE Videos button to open MediaBrowser instead of the native movie library choose the application event option and enter the location of the ehshell program, usually “C:Windowsehomeehshell.exe”. Under Params, set the entrypoint parameter by entering “/entrypoint:{ce32c570-4bec-4aeb-ad1d-cf47b91de0b2}{fc9abccc-36cb-47ac-8bab-03e8ef5f6f22}”. This is the “/entrypoint:” switch followed by the AppID, a slash and the EntryPoint ID. For example, to change the button to run Open Media Library the parameters would be, “/entrypoint:{3f0850a7-0fd7-4cbf-b8dc-c7f7ea31534e}{1044a023-44cc-401c-a5df-4f58601f1f57}”.

Once you’ve set the application and parameters be sure to press the Apply Change button to commit the changes you’ve made to Intelliremote’s settings. That’s all there is to it! Relaunch Windows 7 Media Center and give it a try. As long as the HID Access service has been disabled you should now have total control over the Media Center remote using the Intelliremote settings. Note: Should you notice any remote buttons stop functioning properly inside Media Center you likely need to use the Learn Code function for that particular button inside Intelliremote.
