My Product Suggestion is to provide the option to fully activate Silent Mode for a period of my choosing, i.e. until I chose to reactivate.
Like many others here in this forum, I find the number of pop-ups Norton generates very irritating and I do have Special Offer Notifications switched off in Administrative Settings. I therefore use Silent Mode to prevent them. However, the choice of Silent Mode duration periods are very limited and restricted to a maximum of 1-day. Even when Silent Mode is activated, some pop-ups still appear. Also, when 1-day is selected as the duration, it often only lasts just a few hours.
