Hi folks, I'm having an issue with Norton's latest NIS, I have had it un-installed and re-installed three times now by the tech team on live chat. But after a day or so, when I start up the pc (Vista 32bit) it shows a red cross on the Norton logo instead of a green tick which some time will right it's self after a few seconds. Now I'm also getting an error message 8506,421. Please don't say un-install and re-install. I feel if it's come to that, it can stay un-installed and another product can take it's place. Thanks guy's
