Hello,
I have attempted to uninstall my Bitdefender 2011 (which appeared successful except for a step about "executing additional tools" or something like that). After the uninstall was finished, I then installed Bitdefender 2013.
Now I am receiving the above mentioned "Bitdefender Security Services are not responding".
My computer is using Windows Vista Home Premium and has SP2 installed.
It is a 64 bit OS.
Looking forward to your response!
Thanks,
Chad
