there's some problems that makes me can't use bitdefender 
1- upload problem:
i reported before download problem here
http://forum.bitdefender.com/index.php?showtopic=26965
and this problem fixed but now same problem for upload now, bitdefender continue the upload after i close the browser and make my upload very slow( like 5 K/s ), if you want a video that's easy but this problem like before ( download problem ).
2- VMware Workstation problem:
when i run vmware my pc stop working many times for about to 5 minutes every time or more i can't do any thing except waiting vmware to close, at this time bitdefender don't use much ram or processor just the hard drive, this problem solved with 2012 beta but when i tried the final same problem back again.
in this problem i tried all version of bitdefender from 2009 to 2012
3- slow pc problem:
bitdefender 2012 the best bitdefender product until now it's more faster but i compare it with other product in same pc ( my pc ), with other antivirus product i can run vmware and firefox and yahoo and video do many things in same time without any problems but with bitdefender i can do one or more only, why you don't make bitdefender more speed so all kind of users can use it?!
