I get e-mails with an obviously bogus e-mail address with an "Official"-looking Norton/Symantec webpage link. I would recommend that users NEVER click on links like this, instead accessing any updates, purchases, etc. through the real Norton website which will always be in the top 5 web links on Google, Bing, etc. and NOT e-mails. Many times Phishing or other malicious disguised e-mails will show a non-company e-mail address, but not always.
