I have been using NIS for years but switched to Norton Security Deluxe last year. The last several weeks both quick scan and full scan will not schedule. I have to scan my computer manually. I have contacted support, uninstalled and reinstalled NS and I still can not schedule scans. The full schedule is once a week, 11 pm, with AC power on and was working. The quick scan does not scan after an update. My computer will go days without any scans. My sleep mode is set for 4 hours. Thankful for any help.
