I just downloaded the trial version of NOD32. During installation (I cancelled did not complete install) i was instructed to uninstall any current Anti Virus program or bad things could happen. I'm currently running Norton Anti Virus with auto protect enabled; is it absolutely necessary to uinstall this? Isn't there some way to just stop Norton from loading without uninstalling it. If i did proceed with the NOD32 install what the worst that could happen?
