Hi,
I just upgraded my computer to vista x64 ultimate and everything was fine until I installed bitdefender internet security 2009. Before Bitdefeder everything worked now I can't get to my system resources and vista runs very slow. I have unistalled and re-installed it and still works the same. Also it took forever to shutdown last night. Is there a way to fix this? I have it on an amd x2 3800+ system with all the vista drivers installed.
