Can someone tell me why NAV 2003 update 02-26-2004 does not recognize this file as a virus.

In case you are thinking this is a f/p of Adaware, think again.

Is my install of NAV corrupt or is Symantec just slow on detecting this one?

Forget it. I will have to look at my settings. When I tried to move the file NAV found and removed the virus.
