Symantec NAV 7.6 Corporate Edition has a MAJOR fault when running on XP.
It simply will NOT scan floppies on the fly (even with the most
restrictive settings enabled) This is a bug that has been confirmed by
Symantec (after 3 months of sitting on their bum doing absolutely NOTHING
about it)

I still haven't seen a solution - other than dumping the product yet.

Below are snippets from actual Symantec tech support e-mails.

"With 7.61 on the XP Pro machine (your Vectra) we did not catch the virus
at the floppy, however we did catch it when we burned it to CD.

I tested with 7.61 build 45 on XP PRO.. not your machine.. we did not
catch the virus at the floppy.
I tested the 8.01 on a machine that wasn't yours as well and it worked as
designed.

I am thinking at this point there could be a couple of things happening.
1)XP PRO does something between NAV 7.6x and the floppy
2) XP PRO does something to Nav 7.6x "

I think they should advertise this widely but.....
