Scan with AVG

I'm trying to get a context menu item to work that will scan a single file, a selection of files or a whole folder with AVG anti-viurs software. If I allow the Explorer context menu items to be displayed there's one called Scan with AVG that works this way, but if I disable these items and try and add my own I can only get it to work with a single file.

I've tried

ContextMenu ID = 132

on All files, All files and folders and All folders. No matter which one I choose, it only fires up AVG and scans if a single file is selected; otherswise it does nothing.

How can I get the equivalent of the Explorer context menu item to work in Dopus without enabling all the Explorer items?

Maybe this is a better/easier way:

Thanks, that's better.
