I have a problem with Norton Security Suite: Today, when I ran LiveUpdate manually, I got the message that "Web Protection Definitions failed to complete" due to incompatibiliites with Malwarebytes' Anti-Malware. Even worse, I got the news that Norton 360 v. 20.4 was released ten days ago that would fix the compatibility problems with MBAM, and it's so disheartening that v. 20.4 does not apply to the Norton Security Suite I have! When will NSS v. 20.4 be released? 
Hi Debbie,
I see you have already seen and responded to my reply on the Comcast Forum. Yes, same person - just a different user name!
