What is in-depth analysis? How often should i use it? What is the different between in-depth analysis and the on demand scan i have set up using BLACKSPEARS tweak? I also see that there are different versions of nod32 coming. My version is 2.50.19. When a new version comes, is it called 2.50.20 or is it 3.0? Do i have to download the new version when it is realeased or will my nod32 automaticly update itself? How often are new versions realeased? As you probaly see i dont know much about these things, and my english arent that good. So if anyone understands what i`m writing about and want to give me some answers.. THANK YOU!!
