I can't remember ever getting an alert  from NAV 2003 while browsing in IE 
6/5, but then I'm the zealot with his ActiveX/Java and a bunch of other 
stuff turned off. Now while doing weekly scans, I've found & cleaned things 
in the cache that never got rendered by the browser.

One would think that NAV stands between the incoming data & IE, therefore 
should be able to deny access to the file & remove it. Biggest surprise 
years ago was when a sample of the1st IE exploit changed files on my system 
& NAV at the time never raised any flags. Ever since then I've been using 
dumbed down IE settings & custom security zones.

Emptying the cache is good & bad: Good in that there aren't a huge number 
of little files to be scanned. Bad in that if a site gave you an infected 
file, you wouldn't know at all. When scanning from a boot CD, I always 
clear the cache of suffer the potential hours of scanning temp Internet 
files w/ HDD caching.

Won't be trying NAV 2004 w/ it's activation nightmares here, almost not 
even using 2003 after it crapped out a week before my subscription was to 
expire and taking my network stack with it (symtdi) doing an uninstall.
