Not really sure why this error came up. But if I change 
@bannedF = ("c:\\win32app\\toolkit",
            
            "c:\\winnt",
            "C:\\WINNT\\system32",
            
            "d:\\perl",
            "d:\\brossad");

[download]
to 
@bannedF = qw( c:/win32app/toolkit c:/winnt C:/WINNT/system32 d:/perl 
+d:/brossad );

[download]
it works.

Also my $folder = "c:\TEMP\sdfs"; should be my $folder = "c:\\TEMP\\sdfs"; or my $folder = 'c:\TEMP\sdfs';

Update: Looking at my Perl reference it looks like it is interpreting \p as a property.
