Has anyone else had problems with Norton Internet Security stopping at regular intervals (every week in my case) since Windows 10 upgrade? Every time I login to my laptop, I get the message come up that my Norton product is not compatible with Windows 10 and when I try to open it, I get error message 8504, 100. Every time, I have to go through the rigmarole of uninstalling and re-installing & running Live Update etc. etc...... Therefore on New Year's Day, I'd had enough and got a Norton support technician to remote in to try and resolve it via chat, but all they did was exactly what I'd been doing every week for nearly two months and now, 7 days later, it's stopped again and I've had to go through the whole uninstall/reinstall thing again. I'm really fed up.
