For Online Computer Support, Ask a Computer Technician
Hi there, I am Cris and will be glad to assist you.
I can assist in upgrading your PC to Windows 10. But just to inform you have reached JustAnswer.com a site that offers Computer Proffessionals. The cost of Norton is a separate from Symantec, however they do not assist with any OS upgrades.
I would recommend a much better antivirus called Eset Nod 32 it is $40 for 1 PC/1 year and ranks first in detection and removal rate.
If you would like remote support on performing the upgrade I can offer you that or just give you written instructions. Let me know if you would like to proceed?
