OK thats a weird one to be popping up.
The "Run As" command is for administrators on a network so that they dont have to log off the user (limited user on a network) to perform administrator tasks.
I dont know how computer savvy you are but what I would do is try and disable the Run As feature as you dont need it.
To do this you have to edit the registry by clicking on start- run- type regedit (I would backup the registry before going any furthur).
Locate the following key on each machine:
Then create a new DWORD value named HideRunAsVerb and assign it a value of 1.
(to craete a DWORD right click any where in the explorer folder - New -DWORD Value)
