Removing Items from context menu

A while ago I had installed a trial version of VMWare Fusion, which I have since removed from my computer.

One change that VMWare fusion does is to add "double entries" to the "open with" menu when ctrl-clicking on a file.

Here's an example:

If I accidentally click one of those entries that says (Mac - Boot Camp Partition.app) it tries to open the now non-existent Fusion.

Is there a .plist file somewhere which I can edit to remove these entries from the menu? It's messy,and kind of a pain.

Thanks
