23 sub increm
     24     { $mid = ($mi + $gap) % 60; }

You shouldn't define subroutines that only have side effects. In other words, increm() returns a value and you should use that returned value to assign to the variable $mid. 

     44     if (open CAC, "+>", "cache.html") {

[download]
You are only writing to the CAC filehandle so there is no point in opening the file for reading as well. 

     51     my $filetobecopied = "cache.html.";
     52     my $newfile = "nmapresult.html.";
     53     copy($filetobecopied, $newfile) or die "File cannot be cop
+ied.";

[download]
The file you opened is "cache.html" but the file you are trying to copy is "cache.html.", notice the difference in the file names. 

     40     chdir "$pathofnmap";

     42     chdir "C:/Documents and Settings/Wxp/Documenti/pubz";

[download]
Like open() and copy() in your program, you should verify that chdir() worked correctly. 

     55     close NMAP;} else {die "Impossibile aprire Nmap $!\n"}}

[download]
When using close with a piped open you should verify that the filehandle closed correctly.
