Hiya,
It might see StarForce as a threat for the PC. StarForce is our protection system which 'binds' itself to the system specs; it takes a snapshot of your PC specs to make sure that your license key can only be used on that computer. It doesn't do anything with your pc itself, so no harm there although bitdefender might find that malicious.
Rest assure, we have no intention to spread malware or Virusses with our software!
Kind Regards,
Team Citor3
