The answer is yes.  Norton does flag that file as a threat, and once you 
download it and attempt to install the .exe file, your computer will say that 
it cannot be found, and you will see Norton giving you a notice in the lower 
right of your screen, saying that it is analyzing the file.  It then turns from 
yellow to red, with a big "X" saying that the file was deleted and the threat 
is resolved.

This is where we all blurt out a colorful metaphor. 

It is at this point that trust is involved, that is, that Elecraft would not 
put a malware file on their server.  I think we can all feel safe here!

In the box in the lower right of your screen that I mentioned above, there is a 
link that says "details".  Click on this.

In the next box, the details of the threat are listed, and there are links at 
the bottom of the box.  Click on "Restore" or "Restore File".

You are then asked if you are sure that you wish to restore the threat, and 
that you want Norton to ignore that file in the future.  Click on "yes".

The file will be restored, then double click on it and install the P3 utility.  
Norton will then leave it alone.

Norton has become a bit more aggressive over the last several years.  I really 
cannot say that is a bad thing.  I'd rather deal with the hassle above than 
deal with a virus that trashes my computer and files.  YMMV.

I'm not certain if there is anything that a developer can do to prevent Norton 
or other anti-virus programs from attacking their files, whether it is a 
digital signature, or something else.  None of Elecraft's other utilities are 
considered a threat by Norton in my experience.

Subject: Re: [Elecraft] Norton and P3 Utility

I have seen numerous reports of this particular Norton heuristic showing up in 
what smells like false positives in many cases, although you can’t just 
discount the possibility I suppose.  Neither Kaspersky nor BitDefender have 
ever found anything awry with P3Utility on systems I use.

You can send the exe file to Norton, supposedly for “further analysis” at 
https://submit.symantec.com/false_positive/ 
<https://submit.symantec.com/false_positive/>.  Whether or not they actually do 
anything with it is anyone’s guess, but I‘ll take them at their word that they 
might at least put P3Utility in “exonerated” status if they find nothing wrong 
with it.  I got tired years ago of Norton spending most of it’s time just 
getting in the way, that I dumped it.  YMMV …
