Computer Security Hi Lclucky (you're tempting fate with that name)
I am just as paranoid about viruses, worms and all manners of malware as you are so I have adopted a policy of not downloading exe, pdf or any other type of compressed file or program from the gnutella network. Simply because they are more likely to be booby trapped with malware. Also, just because you have NAV, just like I have, you could find that you have been caught by a virus or such like that Norton haven't yet released a definition for.
I, personally, only download exe's, etc. from the maker's web-site and nowhere else.
The only thing you can really do, and it will NOT give you an iron clad guarantee, is to run your NAV on each file as it is downloaded.
Good luck
