i have not tried the password protect function in bitdefender might try that on the next system i build to see what it does or doesnt do. i like bitdefender cuz it just does what its suppose to do and nothing more. the other product that is very good in my opinion is zonealarm security suite with firewall, antivirus and spam control and spyware protection. not sure the spyware is as good as say spybot but za is quite effective. i use on my main system and it also just does what its suppose to do and leaves you alone. good product.
