"Also I don't see any options as there used to be about when to run scans i.e. time and how often etc."
You could put a trigger in the task scheduler, but, if the message is irritating, why not turn off the messages in the action centre. You could also turn off the warning in the notification area. I know they are there to help, but they are, at the end of the day, only warnings, not real protection
But, only my own observation, you do seem a little over endowed with security programs?. Is Defender and the windows firewall still actually running? I would have thought, with the other programs installed, they might have been automatically turned off.
