Thanks BOAC,
I could be barking up the wrong tree but as I said if I try to interfere with the remaining files the computer goes on a go slow until I leave them alone and just occasionally they threaten to format the C drive!!!
Anyway, here goes.
FSX puts a folder in the C Drive - Programme Files - Microsoft Games. I un-installed it using the FSX programme provided. After deletion I was surprised to find that FSX (Parts of it) was still there in the same folder. (They might have nothing to do with FSX) I thought perhaps some virus had got onto the computer and hidden itself very neatly in there). Nothing shows up on my security system but if I try to touch/move/delete/shred my excellent spec machine grinds almost to a halt.
The file name is simobj~1.sh
I use Windows XP and your other questions dont really effect = The computer is working fine in all respects until I try to delete those files.
Sorry to be a pain, many thanks
