If you are running 2010 and have VBA in password to open protected .xlsms then they should probably be in a trusted location if you want the VBA to run. (I didn’t try very hard but there didn’t seem to be an easy way to trust the doc, maybe temporarily taking the pw off it, trusting it, then redo pw, would work).
Unless you have AV that can scan them (which products do?).
