Someone please help...duplicate windows files

About once a while I go to start->c:/ and there are some duplicate Windows files that have "squares" in place of the "o", the "d", and other letters...also in the Windows folder "system32"

I delete them and they always come back...there are usually three "Windows" folders in c:/ with two with the squares....and the same in the windows folder under system32.

I have reinstalled windows, run av, anit-spy, etc.....


Please help

Basically a [square] represents an unknown font e.g. Chinese characters without a Chinese add on are all [squares].
