I have recently switched to Bitdefender AV from two different competing products (one on my desktop and a different one on my laptop). As a basic security precaution, I always run my windows user as a standard user and not as an administrator.
Bitdefender is lacking some usability features that make running as a standard user somewhat painful. Firstly, if an infection is found and the user does not have access rights to this file, it will not be cleaned. This is a real deal-breaker. It should run in elevated mode and have the capability to remove/heal/clean everything on the hard drive. One needs to log off and then log in to the administrator account to be able to complete any disinfection. Other products handle this much better than Bitdefender.
Secondly, alerts cannot be cleared by a standard user. Again, one needs to log out and then login as the administrator in order to dismiss the alerts (which can frequently be as trivial as a "install the windows updates" type of alert). While not critical like the disinfection issue, it's a heavy usability penalty.
I would recommend that you investigate making the standard user experience a little easier.
