How Do I Upgrade from BD 2008/2009/2010 to BD 2011?

If you are using BitDefender 2008, 2009 or 2010 you can upgrade to the 2011 version by:

  1. Installing it directly over the older version with the installer provided. If the older version was registered, BitDefender 2011 will "remember" the respective license key.
  1. Removing the older version, restarting your computer and installing the new version.  The product settings of your previous version will not be saved.  Please use this upgrade method only if the first option fails.
