For our other readers, this is a more legible version. 

use warnings;
use strict;

use File::Find;

my ($recent,$nom,$rep);
my $line;
$rep = 'D:\\';

sub plus_recent {
    return unless -f;
    return if defined $recent and $recent > (stat($_))[9];

    $recent = (stat(_))[9];
    $nom = $File::Find::name;
}

find(\&plus_recent,$rep);

print $nom;

#open (LOG,"<D:\\log.log") || die ("Erreur d'ouverture de TOTO") ;
open(LOG,"$nom") ;
my @LogFilePosition=<LOG>;
close(LOG);

foreach $line (@LogFilePosition) {
    if ($line =~ /CHAINERECHERCHEE/) {
        print "C'est démarré !!";
    }

The only thing I have to add to the other advice you've gotten is that you might want to add a newline to your print there. 

print $nom, "\n";

Now that I look a little more, you might want to check that your open succeeded as you do with the one you apparently commented out. I'd write it this way: 

open my $log_fh, '<', $nom
    or die "Can't read '$nom': $!";

That way you get a clear error message if it fails.
