I noticed that a number of people already posted about this, and have gone back to 2011 or removing BitDefender completely.
I'm also considering it.
Ever since 2012 was installed, even opening up my web interface to a firewall (for example) is extremely slow. It's faster for me to walk to another computer in another building (running Avira, Kapersky, Norton, etc.) and open up the same browser (chrome, firefox, IE, opera, safari) and complete all the programming before Total Security even brings up the login page (a simple html page)
I'm running 15.0.37.60
Any idea when this will be fixed?
