I have rebooted both the router and the computer, used a recovery point, etc., etc., and am unable to get on the internet. I have tried to uninstall Norton Internet Security, but it won't uninstall and the product version is 21.5.0.19, different than the "error message of 21.6.0.32. Have exhausted my knowledge. Help.
