Surely, Binocs, your vision must be 20/20 (or 6/6, depending on which side of the pond you are!!), but did you say Norton on a PC? I thought the subject was viv-a-vis the Apple Mac!
On the Mac, there is absolutely no confusion that the Norton A/V has ever created for me.
I do keep getting various files on pen-drives from other people -- especially PC/Windows users, and the number of times Norton AV has caught viruses is quite a few.
As I said, it is your environment, you know it best -- and, as always, it is always your call!!
cheers
