This is a quote from an email I was sent by a Bitdefender Technical Support Engineer regarding why Bitdefender will not update. And I quote "...One of the causes due to which this issue occurs is the fact that the v_live_s.xml file from BitDefender becomes corrupted. The file is part of the BitDefender Update module and holds the information regarding the settings of the module. At this moment we do not know exactly how and why the file became corrupted...." I have one question. Why would Bitdefender sell a product that has a corrupt file?
