If the certificate isn't there or looks different, your brother downloaded a shady, possibly malicious copy somewhere. This is what it looks on my legit copy when I double click the certificate: I can't screenshot the windows dialog but a different way you can check the signature is right clicking the installer, going to 'Digital Signatures', and seeing if the signature is there. If it's not signed, something is definitely wrong. Is your brother 100% sure he downloaded bluestacks from the right place? If he has a legit copy, it will be signed by 'Bluestacks Systems, Inc.' when you try to launch the installer, and windows pops up that dialog of 'do you want to allow this program to make changes to your PC'. If you're in the USA and the login is from like Russia or something then something is definitely up. Is your brother using a VPN, or is the area somewhat close by? But I would expect the area to be +- in the area you live in, or at least where your ISP is. Google does usually e-mail you about new logins from the Bluestacks emulator. They have their revenue streams like advertising and the whole 'game platform' shebang, it would be an utterly dumb business decision to start hacking people's accounts on the side lol.
