Currently I am running the trail version of the NOD32 antivirus and I plan on buying a license and had a couple of question. First, can I insert the license key directly into the version I am running or do I need to uninstall and reinstall? Second, I am running the factory default settings and was wondering was that suffice or do I need to change any of the settings? I like how NOD is light and responsive so I would not want to change anything that would slow down its performance. Thank you for your time.
