Hi @SILVIOD_MEDEIROS ,
Support can be reached via technical resources and docs, by chat (possibly translated), through social networks or by telephone from the page:
https://support.norton.com/sp/en/us/home/current/contact
The number is different depending on the country. You will get it after answering a few simple questions about the difficulty that is leading you to contact support.
This community of Norton users can also assist you and answer many technical questions.
Sincerely
Guillaume
