After getting no support from the "support" line I started mucking around with BD2010 on my own. I had complained repeatedly about how vsserv.exe would commandeer my memory resources and my machine would seize for up to 25 minutes at a time (would have been more but I rebooted the machine.)
Anyway, ON MY OWN I figured out that disabling the "antiphishing protection" releases a HUGE chunk of memory. When I am running with antiphishing enabled, I am watching vsserv monopolize anywhere from 85-97% of my memory- which at 8 GB is a pretty extensive level of processing. When I kill the antiphishing protection, I am able to get vsserv back into a tolerable 12-14% range.
Not a solution but at least it will work until BitDefender decides to do something besides apologize with a form letter and send me the link to the uninstall file.
(How about it, BD? Are you going to delete this message too?)
