Hiding protector signature !

EXECryptor 2.x can't detected tools like PEID and can't produce stable signatures in protected exe's

some file identifiers uses a few started bytes form executrable to find out the protector type, if you want to hide this you can manually change the first code (that is hard to do) or you can write own protector , tha's the way too
but now, PE identifilers uses more advanced techniqes to detect the protector..
