Just installed Bitdefender 2016 Total Security, from the official site no less.
I reboot after the installation, wonder why my internet is so slow - check resource monitor but it doesn't show up so likely the connection was established after boot - after 15 minutes of trying to find it i uninstall Bitdefender and the constant download hogging my internet is gone. Mind you with the time that passed and my internet speed (25mbit) it will have equated to a couple of gigabytes of downstream.
Will refund immediately.
