Constant Scanning

For the last week or 2 my android phone has been running a scan 20+ times per day. Before it only scanned on demand or if I added or updated an app. 

I went through all the settings and can't find anything to change. It's set up to run weekly scan. I think this has to do with the latest update from Norton. 

All this scanning is using up battery time. How do I fix it?

Thanks
