My NOD32 version 2 is about to expire. I have been running this version for four years with only one glitch. But now it is time for an upgrade. When I download the latest version of 4 will it automatically uninstall version 2or do I have to this manually before installing 4? Will I need to configure or does version 4 do this automatically? Sorry for the noobish type questions but the thing I love about version 2 is once it was installed and configured I didn't have to worry about it for four years.
