Why does Norton malfunction?

Hello. I have been using this service for about one and a half month and paid for the annual membership. It had worked fine for about a month and from a couple of weeks ago, it’s a bit acting up. For instance, as I refer to the report, the wifi security section showed it had identified 5 wifi connections but out of the blue, it became 2. What’s more, in the internet security sector, the domains it confirmed as safe or hazardous are fluctuating every day! It used to multiply in figures like 4500 went to 4512 but now, it dwindles from 4500 to 4490 or something, which is weird. Is my norton 360 protecting my i phone or not. I would much appreciate if you clarify this glitch.
