Looking a little more into this and I suspect it's going to be one of those MS "issues" that isn't really a problem after all.
The file shows dependancies as
(Date and time created 11am 17th Aug 2009 which was when I was doing the clean install of Vista... PC hadn't been on line at this stage apart from windows update.)
and in turn finding those show they are an MS application related to unicode for XP
It would be interesting to know if anyone else has the same files showing.
I don't know why it say damaged as the file status.
