Norton Internet Security 2011 was disabled (either by a virus or other form of malware) and requires me to activate again. I've hit "Activate" but the "Number of days Remaining" was reseted. I didn't trust that this was right so I uninstalled the software removing all settings and reinstalled. I reactivated again and ran live update and then ran a complete system scan. Nothing was found. Can I trust that the software is working properly or do I need to format everything and reload all my software? What to do? Thanks!
