Look at the loops. 

while ($line = <FB>)   # every line
    foreach (@array)   # every field in that line
        for ($i=0; $i<=$#dbarray1; $i++)  # items in @dbarray1
#           if ($array[10] =~ m/Scan/)
            if (/Scan/)

The first condition, ($array[10] =~ m/Scan/), will look for "Scan" in field 10 (the 11th field) n times per line where n is the number of items in @dbarray1 times the number of fields.

The second condition, (/Scan/), will look for "Scan" in each field n times where n is the number of items in @dbarray1. This is because the regexp match is not bound to a variable, so it's matching against $_, which is being iterated by the "foreach (@array)".

I suggest you check for "Scan" right after you split into @array: 

while ($line = <FB>) {
    chomp($line);
    @array = split /\s*\|/, $line;

    if ( $array[10] =~ /Scan/ ) {
        # happiness ensues
    }
