Words blocked by NAV software?

Hello,

I realised that on some pages (e.g. Amamzon.com), some images could not be seen on one of my computers. Similarly, even for the sites I developed, I was not able to view some of the images unless I renamed them.

I was told that this has something to do with the Norton Antivirus Software blocking out certain words.

My question is:

1) Where can I find that list of terms on the software?
2) How do I customize the list so that I will be able to define what the software blocks and what it shouldn't.

Any idea?

Thanks
