why have to operate win8.1 on Norton 360 without protected zone. Is it compromising my security?

I updated windows to 8.1, found i could not get Identity safe open, I followed Norton advice to uncheck the "enable security protection". via Tools menu and yes it worked but leaves me with constant messages that I have no security protection enabled. Does this put my computer at risk? I checked my 360 is up to date and it confirms it is. Is there anything else i need to do? This move does seem like a unsatisfactory work round or fudge, surely Norton had access to win 8.1 to do testing before issue.
