Norton 360 Error: "8506,421" appears on my Norton product
I have used Norton 360 previously for one year and there have been no issue and therefore i decide to renew when it expires. However after a few months of use, the error message occured. I uninstalled and re-installed for quite a number of times including the use of norton power eraser but the error message still occurs. Now my laptop is unprotected, please advise as i have bought the 2 years subscription for this
