How to add a new traffic rule that does not "...override all application rules"

Hello,

 

I'm not an 'experienced user' and rather than learn by trial and errror, I thought I'd ask first,

having been unable to find any existing thread that answers this question:

 

Is it possible to add a new Traffic Rule so that I can download a plug-in from www.autobusinessevent.com

without at the same time "creating a new general rule" which "will override all application rules " (the quoted wording

is taken from the warning notice that appears at the penultimate step in Norton in the process to add a new Traffic Rule).

 

I don't want to create a new 'general rule', just a specific rule which will allow me to download the plug-in

 

the reason I need a rule (i think it's a rule i need) is because when I attempt to download the plug-in from autobusinessevent.com Norton identifies a "medium threat" called WS.Reputatuion.1 and immediately removes the file.

 

Thanks in advance for any help.
