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
