Hello. I recently tried installing Spybot and McAfee on my computer together. I am running Vista Home Premium on this one. When, I installed it my computer started acting really weird and which basically led me to believe as if there's some sort of compatibility issue here, maybe? Well, when I installed both of them on my old computer running XP Home Edition, they worked perfectly fine together. So, I was hoping; would someone please explain to me what's wrong here?
