After running the first removal too (nonav.exe), re-started computer and used another tool called Norton Removal Tool (v.20.0.0.21) available from that link:
https://support.norton.com/sp/en/us/home/current/solutions/kb20080828154508EN_EndUserProfile_en_us;jsessionid=0C714D17D518A0AAF037FE92B0B5F993.4?entsrc=redirect_pubweb&product=home&pvid=f-home&version=1
It did more cleaning of SAV remnants left behind by the first tool. The SAV file and folder have been removed. The Symantec AntiVirus still appears under Add/Remove programs. Also when launching MS Outlook it complaining about not finding “C:\Program Files\Symantec Antivirus\vpmsece4.dll” add-in.
Cleaning SAV off the system probably has no relevance to that forum, I just have do to a manual registry cleanup when I have time. The important thing is that Avast! Free Antivirus 8.0.1489 is working fine.
