Thanks for your response and also to Paolo's response.

I'm ready to help as far as I can with my limited skills.

The "vendor's form" ( specifies that a corporate email adress is mandatory to make a proactive whitelisting:
Software Whitelisting Request

This form is for use by Vendors wishing to have their software proactively whitelisted by Symantec.

Important information
• Whitelisting is file/version specific. Future versions will not be whitelisted by default. • New versions of your software should be submitted for whitelisting as they become available. • For identity verification, a corporate email address is mandatory. Requests from free email domains will not be processed.

In fact, the "vendor's" form is very much alike the user's form ( and the result seems also to be alike.

The only difference is that the user's form begins with the question "When did the detection .. occur?"; one of the possible responses is "the options provided do not apply".
Than you have to specify the kind of Symantec product.

I recall having read that the recognition is "cloud" based, whitelisting for one product holds for all "cloud based" Symantec products.

So there is the possibility to just fill the user's form (which is in my reach) in case there is no other way!

Thanks Paul,

Yes indeed it looks like every single version will need to be whitelisted.

It would be interesting for us to upload every release, but it looks
like it's a manual process that someone will need to take care of (at
least it doesn't look like it's a scriptable API):

It also looks like code signing would be an alternative, but from a
quick look at the page , this
mainly looks like a process to generate business for some CA with no
open alternatives.
But if someone has more experience in this area, it will be interesting
to hear insights.

I think the most sustainable approach is if

  * someone volunteers to manually upload the files after new releases
  * or possibly (if it helps...) someone sponsors a certificate

Thanks Matthias,

I just received the answer of Symantec (Norton), here are some excerpts.


Upon further analysis and investigation we have verified your submission
and, as such, the detection(s) for the following file(s) will be removed
from our products:

     File name: qgis_bin.exe
     MD5: 99002dab0a0525a941b4a473fe4b058b
     Note: Whitelisting may take up to 24 hours to take effect via Live

If detection persists, please contact support:

If you are a software vendor and would like to upload your software for
proactive whitelisting, please complete one of the following forms:

* Otherwise:

Does it mean that they whitelist just one version of QGIS (in relation
with the signature MD5)?
Which means that every new version should also be submitted to them?
(luckily, the procedure is easy and not time-consuming).

They also recommend a "software vendor" procedure, which is beyond my

Regards and thanks to all the developers for the marvelous development
of QGIS,

Thank you Paul,

We have received similar reports in the past already.

I think what you have done is the best approach: notify the antivirus
producer about false alerts as a user and provide them with the required
information (qgis-bin.exe etc.) to investigate the problem and update
the heuristics or white list accordingly.

With the information available from the general description of the
heuristics, there is normally not a lot we can do to "solve" the problem
from our side. If Norton asks more information, please just post again
either on this list or on the qgis developer list.

Thanks again

Hi all,

For info to Norton Security Users,

Using QGIS 2.18.1 on Windows 7 sp1 64 bits.

Norton deleted twice, without warning, qgis-bin.exe + many .py files on
my computer + modified many registry entries.

Message was "WS.Reputation.1", linked to the so-called SONAR function of
Norton Security.

This is how it works : "WS.Reputation.1 is a detection for files that
have a low reputation score based on analyzing data from Symantec’s
community of users and therefore are likely to be security risks."

The Norton (french-speaking) Assistance  confirmed me it is a false
positive. I asked them to put QGIS on the White List.

NB: this is not the first time it happens for QGIS, see:

Afterwards, I submitted also a demand for whitelisting, as a Norton
user, on the Norton website
(, where
qgis-bin.exe can be uploaded for testing.

I hope this will prevent any other disturbing false positive on Norton
products. Any suggestion?
