annoying Norton popups

I am trying this Norton Mobile free for a month but I keep getting annoying popups about all sorts of "warnings"which are bogus. I am also running Avast and WinPatrol. I am seriously thinking about deleting this Norton product because of the annoying popups despite all the good things I have read about it. If this was fixed so it didn’t constantly interrupt my work I would have likely bought this product. But as it is I can’t tolerate the frequent interuptions. Are there any fixes? Why can’t it work in the background like Avast or restrict its popups to real potential threats like WinPatrol?
