The never-ending, relentless, obtrusive POP-UPS in the lower right hand corner of the screen... I just finished a chat session about how to finally stop them. Long story short -
First, under 'Administrative Settings', turn OFF 'Norton Task Notification' and 'Special Offer Notification'.
Then, in CLASSIC mode, click on the magnifying glass in the upper right. Type 'NOTIFICATION'. This brings up several different notifications that can be switched off. These options are not listed under 'Administrative Settings'.
This should finally turn off all pop-up notifications.
The rep only told me about the second step after I thoroughly complained and threatened to cancel my subscription. He actually said he wasn't supposed to tell me about that (whatever that means).
Hope this fixes the issue for everyone!
