I don't know if it's a good one. Be sure to scan it with several programs first, to see if it hasn't got any viruses or things that steal your password.
Yeah well it can work fine and then you can lose your account the next day So I say : Check. But you have to decide for yourself.
it might work fine, but it also might contain a keylogger or something, make sure you check it so theres nothing bad in it
