According to perlretut ( here ): 

 The escape sequence \Q ...\E  quotes, or protects most non-alphabetic
+ characters. For instance,

   1. $x = "\QThat !^*&%~& cat!";
   2. $x =~ /\Q!^*&%~&\E/; # check for rough language

It does not protect $ or @ , so that variables can still be substitute
+d.

And perl.com says :
You cannot include a literal $ or @ within a \Q sequence. An unescaped $ or @ interpolates the corresponding variable, while escaping will cause the literal string \$ to be matched. You'll need to write something like m/\Quser\E\@\Qhost/.
So, escaping should work : 
use warnings;
use strict;

print "Yes!\n" if ( '$@' =~ m|\$\@| ); 
# prints "Yes!"

So maybe your regex isn't what you think - try a little debugging : 
use warnings;
use strict;

my $string = '@@@';
if ( $string =~ m|\$\@| ){
    print "Yes!\n";
}
else {
    print "\'$string\' did not match...\n";
}
# prints "'@@@' did not match..."
