My World of Warcraft Launcher's download speed is being badly throttled, and BitDefender 2012 is the culprit. Even with the relevant programs added to the exceptions list and every possible scanning feature disabled, my patch download is maxing out at a dismal 10-15 kbps. I temporarily uninstalled BitDefender to get things moving and the download is now working normally.
Is there some part of BD I may have failed to configure to allow the WoW Launcher to work properly?
